Hi ShortElephant92

This isn't an issue if the user is using a Service Account JSON Key,

Are you saying that when you are using GS python sdk directly it works?

For context, the google cloud storage SDK allows an authorized user credentials.

ClearML actually uses the google python SDK, the JSON is just a way to pass the credentials to the google SDK, I'm not sure it points to "service account"? where did that requirement came from ?
is it from here Service account info was not in the expected format, missing fields token_uri, client_email. ?
Could that be the same issue?
