The bucket does not allow ACLs

If you encounter the following error while rendering a video on Remotion Lambda:

AccessControlListNotSupported: The bucket does not allow ACLs

You are trying to render into a bucket that has the ACL feature disabled and handles its permissions in a different way, for example through bucket policies.

Solution

Pass no-acl to the privacy option of renderMediaOnLambda(), renderStillOnLambda() or npx remotion lambda render.
