Events - Thumbnail Uploading API Error

Upon trying to upload a media based thumbnail to an experience event under the Configure Event page > Event Details > Media, the site returns Response from https://apis.roblox.com/assets/user-auth/v1/assets returned an error code 400 and enters an infinite loading, also locking out the ability to update the event and save other changes or when creating a new event.

This has been reproduced with multiple thumbnails, trying different file names assuming it could’ve been a false flag moderation issue, and trying different file types, resolutions, and sizes.

ROBLOX has been having intermittent connection issues the last 12-ish hours, I recommend waiting little bit longer and attempt your upload again.
For situational awareness, Error 400 means Bad Request.

This has been going on for over a week now, so don’t think it was related to last night’s outages.

Hi sorry for the inconvenience
The team is looking into it. Are you consistently hitting it or it’s flaky?

Also this seems to be 400 bad request. Could you take a look at the inspection to check the Response payload that contains the error message, then we can suggest, thx!

I’ve uploaded a screenshot of this to the associated private DM for the report.

Regarding the consistency, this is happening everytime on any network & account, and was first noticed when we created events last week.

We might locate the issue. Your event name is too long to be applied as the thumbnail title. Can you try to rename your event first (length < 50 characters) then try to upload the thumbnails again?

Let me know whether that works for you. Thanks!

Following up, does it resolve your problem? Feel free to let us know if there’s still a problem

Mark it as resolved and close out for now since there’s no further complaining on the issue after following up.
