Is there a pre-built validation container for testing streaming functionality?

Yes; a streaming validation container is available on NGC here. To use this container, follow these steps using a Linux-based workstation:

  1. Download the streaming validation container from NGC using the link above.

  2. Upload that container to the Private Registry within your NGC Org and deploy it as a function using these instructions.

  3. If you are using the Portal Sample, publish the function and execute it using these instructions.

  4. The following image should appear streaming from your tenant:

How do I change the OIDC claim name carrying the information of the admin group?

  1. Change “groups” to “<your claim name>” in two lines of code:

Note

The claim is expected to hold a JSON array; using a single value might not be supported.

Why am I receiviing “401 Unauthorized” entries in the backend logs?

It is likely the backend cannot reach the OIDC endpoints specified in the configuration file, particularly the JWKS and Userinfo endpoints. Verify connectivity from the backend host or container to these endpoints using the following command:

curl '*'<an OIDC API endpoint you have in your settings.toml>

Note

If your environment includes proxy servers that could block communication between the portal and OIDC endpoints, ensure the appropriate environment variables are set persistently.

export http_proxy=<your HTTP proxy>
export https_proxy=<your HTTPS proxy>
export HTTP_PROXY=<your HTTP proxy>
export HTTPS_PROXY=<your HTTPS proxy>
export NO_PROXY=<your list of URLs that don't need proxying>
If you encounter the error message ‘Failed to load streaming applications - HTTP 401. Unauthorized’

This typically indicates a misconfiguration in your settings.toml file on the backend. This prevents the backend service from successfully authenticating your account with your identity provider (IDP) to retrieve the list of available applications.

If the GET request to the /apps API endpoint fails, an ‘Unauthorized’ error message will be returned.

This occurs when a user has not signed in through the web frontend, which is required to access the Swagger UI.
