A Zebra label does not print. The diagnostic logs show an error similar to the following:
System.Exception: Failed to convert the following from Base64 encoding: 'Not generated due to previous error.'. This resulted in the following exception being generated: System.FormatException: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.
