    Moodle sends an HTTP 200 response back on errors with details in the JSON.
    Below are just a few examples I've run into.

    If it doesn't recognize the structure of the criteria parameter in the URL,
    you get this error message:
    { exception: "invalid_parameter_exception", errorcode: "invalidparameter",
    message: "Invalid parameter value detected" }

    If the web service being specified doesn't exist, you get:
    { exception: "dml_missing_record_exception", errorcode: "invalidrecord",
    message: "Can not find data record in database table external_functions."}

    If the token you're using is related to a Service that doesn't have the
    necessary permissions you get:
    { exception: "webservice_access_exception", errorcode: "accessexception",
    message: "Access control exception" }

    return "Error: {}".format(data)
