AWS credentials to access external S3 bucket could not be loaded
ERROR: 53667
PROGRAMMABLE VIDEO
ERROR
Description
The AWS credentials configured in your account's composition settings could not be loaded.
Media composition has been marked as FAILED and will not be retried.
Possible Causes
If you have specified your own bucket and access credentials, this is most likely due to the fact that the credentials resource has been removed from Twilio.
Possible Solutions
In the composition settings section of your account's console, create and assign a new credentials entry for accessing your S3 bucket or disable the external storage (media will be uploaded to the default bucket).
