UnboundLocalError when trying to authenticate against portal with enterprise login

Question

Hi guys, We are trying to connect to a portal using Python API and we have got some issues with it. The use case here is that we want to authenticate non-interactive fashion to the portal using OAuth on times fashion. Basically we have followed this guide. When we run the code, we see following error: C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\arcgis\_impl\connection.py in oauth_authenticate(self, client_id, expiration) 462 'username': self._username, 463 'password': self._password, --> 464 'oauth_state': oauth_info['oauth_state'] 465 } 466 content = self.post('oauth2/signin', parameters, ssl=True, try_json=False, add_token=False) UnboundLocalError: local variable 'oauth_info' referenced before assignment Code used: from arcgis.gis import GIS gis = GIS("https://{{portalurlhere}}/home", username='{{usernamehere}}', password='{{passwordhere}}', client_id='{{clientidhere}}') print("Successfully logged in as: " + gis.properties.user.username)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Atma Mani‌ Rohit Singh‌ Any idea what we are doing wrong here? Do you think this is an issue in the API?

Hi! Looking at the code sample in the below documentation. Working with different authentication schemes | ArcGIS for Developers Are you able to go through the interactive process when using the below code? from arcgis.gis import GIS gis = GIS("https://{{portalurlhere}}/home", client_id='{{clientidhere}}') print("Successfully logged in as: " + gis.properties.user.username)

Hi guys, I tried to use interactive process as well with the python and I get the same error also in this workflow. from arcgis.gis import GIS gis = GIS("https://{{portalurlhere}}/home", username='{{usernamehere}}', client_id='{{clientidhere}}') print("Successfully logged in as: " + gis.properties.user.username)‍‍‍ Error: UnboundLocalError: local variable 'oauth_info' referenced before assignment Do you think that there is something wrong with how the authentication is set up? Is there limitations on the environments where the python is run such as console / jupyter?

Thanks Rohit Singh‌ for the answer. What comes to the error message, it's definitely not helpful and doesn't provide information to the user what really goes wrong. I would recommend providing a different error message in cases like this.

I will try to see if we can use the same approach shown in the link. Thanks a lot for that.

It sounds like that the if we want to follow the recommended way (use built-in users for scripts) would require us to get one from the customer that is specifically created for the automated scripts. Is there things to know or can you point to the documentation related to the ArcGIS Online configuration that uses both built in and based authentication models?
