I have a IoT device sending data through google PUB/SUB in protobuf format. When I decode data from PUB/SUB message with https://protobuf-decoder.netlify.app/ it looks correct, it corresponds to my object definitions. This is an example of a data that I get in the PUB/SUB ( CAEQneDs_gQaIAjK4Oz-BBIVEKA4GOzMmQEgzLPUAyjIEzD8y_4NGKBWIg0QvvACGgAogPwCMNogKgkQCRgBKOKFqR4= ).
The first issue that I have is why is it not encoded in Base64 format, shouldn't GCP encode it? Another thing is when I try to decode the data I get this exception:
