Title: Users may experience files and media showing as not supported, when uploading in webparts within SharePoint Online
User impact: Users may experience files and media showing as not supported, when uploading in webparts within SharePoint Online.
More info: Some users may see the following error message: ‘This doesn’t seem like a supported image file. Please select a different image’.
As a workaround, users can ignore the error and proceed with the upload; the error message stating the image doesn’t seem supported is appearing incorrectly.
Current status: We’re deploying a code fix to the affected environments and we’re monitoring the progression of the fix to ensure it completes successfully. As the fix saturates, some users may experience relief and once available, we’ll provide a resolution timeline.
Scope of impact: Impact is specific to some users who are served through the affected infrastructure.
Start time: Wednesday, January 24, 2024, at 9:45 PM UTC
Root cause: A recent code change meant to optimize the webpart upload process has caused a timing issue that supplies an uploaded files current state before the service is ready to process it, resulting in impact.
