I am learning Google Cloud Pub/Sub and following this official document : Writing and Responding to Pub/Sub Messages - Python
When I deploy it to cloud, and try to submit the message,
I get the following error :
An internal error occurred: 403 User not authorized to perform this action. (POST https://pubsub.googleapis.com/v1/projects/your-project-id/topics/your-topic:publish) See logs for full stacktrace.
I guess it's due to some authentication problem? Any help would be appreciated.
Make sure that the client you are using is authorized to publish to Pub/Sub. See details here. If your client belongs to the same project as the topic, typically it won't require additional access control configuration. Make sure that your client is authenticated properly.
Here are some notes come from google's documentation Troubleshooting 403 (Forbidden) error :
If you get this error, do the following:
- Make sure you've enabled the Google Cloud Pub/Sub API in the Cloud Platform Console.
- Make sure that the principal making the request has the required permissions on the relevant Google Cloud Pub/Sub resources,
especially if you are using Google Cloud Pub/Sub for cross-project
communication.- If you're using Dataflow, make sure that both @cloudservices.gserviceaccount.com and the Compute Engine
Service account [email protected]
have the required permissions on the relevant Google Cloud Pub/Sub
resource. See Google Cloud Dataflow Security and Permissions for more information.- If you're using App Engine, check your project's Permissions page to see if an App Engine Service Account listed as an Editor. If it is not, add your App Engine Service Account as an Editor. Normally, the App Engine Service Account is of the form
@appspot.gserviceaccount.com.
