Invalid URL for external S3 bucket in composition settings
The S3 bucket URL configured in your account's composition settings is not valid.
The media will not be uploaded until the configuration has been fixed.
Causes
If you have specified your own bucket, this is most likely due to the fact that the URL does not conform to an S3 URL.
Solutions
In the composition settings section of your account's console, set a valid S3 URL for uploading media or disable the external storage (media will be uploaded to the default bucket).
