Invalid URL for external S3 bucket in composition settings
ERROR: 53664
PROGRAMMABLE VIDEO
ERROR
Description
The S3 bucket URL configured in your account's composition settings is not valid.
Media composition has been marked as FAILED and will not be retried.
Possible 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.
Possible 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).
