I recently started using CDF.
I started uploading data to CDF using the OPC UA Extractor and also authenticated Postman with Entra ID.
However, even though I followed Cognite’s documentation step-by-step,
I keep encountering a 401 Unauthorized error.
Attached below are my Postman settings.
Could you help me identify the issue and suggest how to resolve it?
