Service exceptions from Java are not properly decoded in Python client

What happened?

I am using a server conjure service and on exceptions I do not see the errorType deserialized properly.

When a remote exception is throw I get back a payload like this:

  "cause": None,
  "stackTrace": [ REMOVED FROM ISSUE ],
  "errorType": {},
  "args": [],
  "errorInstanceId": "713f5344-e299-41d6-89ff-0244a9a6a8fb",
  "logMessage": "ServiceException: INVALID_ARGUMENT (Workflow:AlertMissingInfo)",
  "message": "ServiceException: INVALID_ARGUMENT (Workflow:AlertMissingInfo)",
  "parameters": [],
  "suppressed": [],
  "localizedMessage": "ServiceException: INVALID_ARGUMENT (Workflow:AlertMissingInfo)"

The errorType parameter is missing above.

My code is not able to deduce the server side errorType for conditional error handling:

if alert_response.failure_response:
        service_exception = alert_response.failure_response.service_exception
        if service_exception['errorType'] != 'Workflow:AlertMissingInfo':
            raise ValueError(f'workflow alert missing info')

Server side is using conjure.java 4.5.0. Client side is using conjure-python-client 1.7.3 build py37_0.

What did you want to happen?

I'd expect errorType to deserialize properly from a Java Conjure service.
