Public key credentials for media tracks encryption could not be loaded
ERROR: 53668
PROGRAMMABLE VIDEO
ERROR
Description
The public key 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 a public key to cryptographically protect media tracks, 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 valid public key or disable the encryption (media will be uploaded in raw).
