Bug Fix: pyrollbar: No access_token provided.

Credentials and authentication issues preventing the rollbar agent in our backend from calling home.

1. Problem

• Although the rollbar access_token is configured with the python variable rollbar_access_token, the agent isn't calling home, and no data are coming through on the Rollbar side.

2. Analysis

• Something must be wrong with the variable rollbar_access_token in line 94 (in the above image).

• After good dozens of minutes, I finally figured out: there are multiple access_tokens at varying levels in Rollbar - one at the project level (for each project) and the other at the account level.

• I was using the account level token where I have to input the project access token.

3. Solution

• Grab the access token from the project.

  • export and gp env ROLLBAR_ACCESS_TOKEN

export ROLLBAR_ACCESS_TOKEN="YOUR_ROLLBAR_TOKEN_FROM_PROJECT"
gp env ROLLBAR_ACCESS_TOKEN="YOUR_ROLLBAR_TOKEN_FROM_PROJECT"

Unbelievable that Rollbar still hasn't updated this code that breaks. @app.before_first_request decorator was depricated from Flask 2.3 Also, there is no function call for init_rollbar(). Rollbar, really?

However, I still get the same error that the access_token is not provided. Well... the error message was quite stragithforward in fact. It's been telling me to "call" the rollbar.init() function.

• Reorganise the Rollbar code.

• Call init_rollbar() under with app.app_context(): function (code fix here).

app.py

# ROLLBAR -------------------------
rollbar_access_token = os.getenv('ROLLBAR_ACCESS_TOKEN')

def init_rollbar():
    """init rollbar module"""
    rollbar.init(
        # access token
        rollbar_access_token,
        # environment name
        'production',
        # server root directory, makes tracebacks prettier
        root=os.path.dirname(os.path.realpath(__file__)),
        # flask already sets up logging
        allow_logging_basic_config=False)

    # send exceptions from `app` to rollbar, using flask's signal system.
    got_request_exception.connect(rollbar.contrib.flask.report_exception, app)


# @app.before_first_request # this decorator will break the code as it is depricated after Flask 2.2 
with app.app_context():     # use this 'with' statement instead. 
  init_rollbar()

# ROLLBAR TEST---------------------
@app.route('/rollbar/test')
def rollbar_test():
    rollbar.report_message('Hello Rollbar!', 'warning')
    return "Hello, Rollbar!"

4. Result

• The error message pyrollbar: No access_token provided is gone.

• I check the Rollbar console and the spans are coming through.
