OAuth 1.0 Dance broken apart for demonistration purposes

I am working on building an automated API test of OAuth 1.0a… the Application has many redirects that I am following to process the OAuth 1.0a dance. My question is the server is ultimately provdiing me with the message “oauth_problem=parameter_absent” when processing the oauth-authorize GET. Here’s a redacted (Redacted values are in bold and italic) example of that message - I don’t see any missing parameter based on the Oauth 1.0a Core specification:

GET https://server/Application/oauth-authorize?oauth_consumer_key=consumerKey&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1630072291&oauth_nonce=XTGpm94I4Ki&oauth_version=1.0&oauth_signature=rmbYP1lZXAx7wnAsc7kr4kjnIdk%3D

Also following screen shot shows the OAuth1.0 settings in postman - note that all environment variables have valid values based on prior steps in the dance

Any pointers on what to try next would be greatly appreciated.

It appears that Postman is removing the consumerKey and secret in the get, which is then coming up as a missing parameter from the server.
