invalid character 'u' looking for beginning of value
 Error: crda exited with code 1

Sometimes, our CRDA actions all start failing at once with this error message. If I had to guess, the server is overloaded since they all start encountering it at the same time.

This message has to be improved. It looks like there is a text response being parsed as JSON.

Here's a different error case which explicitly states it's a server overload with a 504 status.
