Description

Description

Images added to the whiteboard sometimes fail to load or display correctly. This happens with the same account that added the images, as well as with other users opening the whiteboard

Environment
  • OS: Ubuntu Server LTS 26.04
  • Deployment: Docker, Nextcloud-AIO
Webconsole logs
logger.ts:41 [Sync] Local sync failed: DataCloneError: Failed to execute 'postMessage' on 'Worker': async(e,t,n,a)=>{let i;try{i=await uN()}catch(r){return r.name==="AbortError"||r.name==="NotAllowedError"?!1:(c...<omitted>...}} could not be cloned.

Research direction

Start by reproducing local and pasted image failures on the whiteboard using the reported Docker/Nextcloud-AIO environment, then inspect the sync path in useSync.ts and its caller in App.tsx. Use the logger.ts DataCloneError and the browser console trace as the initial clues. Done means uploaded and pasted images load correctly for both the adding account and other users, without the local sync failure.
