Fixes #10541

During a call, the browser console fills with errors even though the call works. This quiets the ones that come from us. It ships with the next release.

Why

• delayed_events 401: the call heartbeat is first sent without the user's token. Our chat server rejects it, and then the request is sent again with the token. Every heartbeat therefore logs a 401. The newer chat library does the same, so this change stays after that upgrade.
• Repeated media errors: when a participant's picture fails to load, the call screen asks for it again every time a tile changes size. Each attempt fails again and logs another error.

What changes

• The heartbeat is sent with the token from the start, so the 401 is gone.
• Downloads of the same picture that run at the same time share one request.
• A picture that failed is not asked for again for 60 s.
• A download that hangs is given up after 20 s.
• All of the call's requests to the chat server now go out one way, through the chat library, so the login token and errors are handled in one place.
• While a call is open, the console line "error while downloading a file" is hidden. This is temporary. It must be removed once the failing downloads are fixed; see BUG: stopped Matrix client keeps polling capabilities with an expired token #10538 (comment).

Tests

The new tests cover the single authenticated heartbeat, the shared and held-back downloads, the timeout, and the hidden console line. Each one fails without the fix.

Not in this PR

• The set_always_on_screen error.
• The capabilities 401, fixed by the library upgrade in BUG: stopped Matrix client keeps polling capabilities with an expired token #10538.
• Why the server answers 500 for some pictures.

Code comments were added or changed in ElementCallWidgetDriver.ts and the new quietDownloadErrors.ts.

Summary by CodeRabbit

• Bug Fixes
  • While a call is open, the specific media-download error is suppressed in the console. Other errors continue to be logged, and normal logging resumes when the call ends.
  • Overlapping downloads of the same media item share a request. Failed downloads can be retried after 60 seconds, and downloads time out after 20 seconds.
  • Delayed call actions, including pending leave requests, are sent through authenticated requests, with page-exit leave requests configured to continue while the page closes.

Walkthrough

Call-widget delayed-event updates now check server support and use authenticated POST requests. The driver records failed media URIs per call. Call setup and cleanup activate and release a filter for the exact media-download console message.

Changes

Call widget error handling

Layer / File(s)	Summary
Authenticated delayed-event updates src/main/userMessaging/calls/ElementCallWidgetDriver.ts, src/main/userMessaging/calls/ElementCallWidgetDriver.test.ts, src/main/userMessaging/calls/CallOverlayHost.test.tsx	The driver checks server support and sends cancel, restart, and send actions through authenticated POST requests. Tests cover endpoint encoding, action bodies, unsupported servers, and session-token authentication.
Failed media download handling src/main/userMessaging/calls/ElementCallWidgetDriver.ts, src/main/userMessaging/calls/ElementCallWidgetDriver.test.ts	The driver records URIs after rejected or non-OK downloads and rejects later attempts for those URIs. Tests cover HTTP and network failures, other media, and a separate driver.
Call-scoped console error filter src/main/userMessaging/calls/quietDownloadErrors.ts, src/main/userMessaging/calls/quietDownloadErrors.test.ts, src/main/userMessaging/calls/CallWidgetFrame.tsx, src/main/userMessaging/calls/CallOverlayHost.test.tsx	The widget activates the filter during setup and releases it during cleanup. The filter suppresses only the exact media-download error while calls are open. Tests cover other errors, multiple releases, and wrappers installed above the filter.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 0af50

A stalled avatar download may remain pending, though the call remains usable. This is a bounded follow-up risk rather than a merge blocker.

Explanation

[#10541] Delayed-event heartbeat: ElementCallWidgetDriver.updateDelayedEvent sends POST /delayed_events/<id> through client.http.authedRequest with the action in the body. The request is authenticated from the first call, so the unauthenticated 401 path of the chat SDK is no longer used. sendPendingLeavesNow uses the same path with keepAlive: true. Media downloads: downloadFile shares in-flight requests per content URI, holds a failed result for 60 s (FAILED_DOWNLOAD_HOLD_MS), and rejects a hanging request after 20 s (DOWNLOAD_TIMEOUT_MS). Console noise: quietDownloadErrors hides only the exact message error while downloading a file while the call is open, passes other errors through, and restores console.error on release. CallWidgetFrame installs it for the call lifetime. The reported tests cover these behaviors. Deviation to note: the issue's expected behavior says a failed avatar is fetched once per call. The code retries after the 60 s hold, so a broken avatar can be requested again during a long call. This bounds the repeated requests and removes the per-resize flood the issue reports, so the core objective is met. The retry is a documented design choice in the PR description. Out of scope by the issue: the set_always_on_screen error, the capabilities 401 in #10538, and the server-side 500 cause. The code does not change these.

Full details: Out of Scope Changes check

Explanation

[#10541] All changes serve the issue's scope. The ElementCallWidgetDriver changes cover the delayed-event authentication and the avatar download handling named in the issue. The sendPendingLeavesNow move to authedRequest affects the same MSC4140 delayed-event endpoint and is explained in the PR as consolidating the chat-server requests of the call. The 20 s download timeout and 60 s hold are part of the avatar handling the PR describes. The temporary exact-match console filter (quietDownloadErrors.ts, CallWidgetFrame.tsx) matches the issue's proposed console patch. The type-only Method import and the CallHostClient type change support the new request path. Tests in ElementCallWidgetDriver.test.ts, CallOverlayHost.test.tsx, and quietDownloadErrors.test.ts cover these changes. No change implements the set_always_on_screen fix, the #10538 capabilities work, or the server-side media fix.

Delete pending leaves only after the update succeeds.

Delete pending leaves only after the update succeeds.

cancelScheduledDelayedEvent and sendScheduledDelayedEvent remove the delay ID before awaiting updateDelayedEvent. If the feature check or authenticated update rejects, sendPendingLeavesNow cannot include that ID in its page-exit request.

Suggested fix

   public async cancelScheduledDelayedEvent(delayId: string): Promise<void> {
-    this.pendingLeaves.delete(delayId);
     await this.updateDelayedEvent(delayId, 'cancel');
+    this.pendingLeaves.delete(delayId);
   }

Live check: before and after

I ran the same scripted walk twice on a fresh local stack: first on develop (9d59fb0), then on this PR (b5d4ce9).

Setup: one user starts a 1:1 voice call. The caller's chat picture points to an image that does not exist. The window is resized every 10 s so the call tiles redraw. The call stayed open for about 100 s in both runs; the call ends on its own when no one answers.

During the call	develop	this PR
Heartbeat 401s	2 (each one followed by a retry)	0
Requests for the broken picture	17	2 (one at the start, one after the 60 s hold)
"error while downloading a file" in the console	17	0
Console errors in total	40	9

What is left in the console with this PR:

• the browser's own "failed to load" line for each picture request (it cannot be hidden);
• the out-of-scope set_always_on_screen and io.element.join errors and an e2ee notice from Element Call. All of these appear on develop too.

The call itself works the same: it rings, and the missing picture falls back to the initial.

[polibb]

Live check again after the request clean-up (0af501a)

I ran the same walk on a fresh stack. The numbers match the earlier run of this PR exactly: 0 heartbeat 401s, 2 requests for the broken picture, 0 "error while downloading a file" lines and 9 console errors in total. The develop baseline is unchanged at 2 / 17 / 17 / 40.

[polibb]

Live check: answered call, closing the tab, reloading (0af501a)

Earlier runs only covered a call nobody answered, with a broken picture. This run covers the paths those runs left open. It is a fresh local stack on this PR's head. Both users have a real uploaded picture, and the other person answers.

Check	Result
Pictures show in the call tiles after the other person joins	Both pictures load. They are still there after 6 window resizes. Every picture request returned 200.
Caller closes the tab mid-call	The other side sees the caller leave 0.3 s later.
Caller reloads mid-call	The other side sees the caller leave 0.3 s later. After the reload the caller is still signed in to chat on the same device, with no new sign-in. A message typed in the chat afterwards reaches the other person.
Heartbeat 401s / "error while downloading a file" lines	0 / 0

Why the 0.3 s matters: the call asks the server to drop a member after 1 hour if the browser goes away silently. A leave this fast means the leave sent on page exit got through. The chat server's log shows that request arriving with status 200, on both close and reload.

Not changed by this PR: Element Call downloads a successful picture again on each resize. This happens on develop too, and the requests succeed, so nothing appears in the console.
