httr2 (i.e., oauth_flow_auth_code_url) seems to disregard the state parameter handed over via oauth_client() or req_oauth_auth_code()
I try to get an authorization token using the OAuth functionality in httr2 using pseudo-oob (another reference). I am almost there, but in the final step, when I enter the access token manually in the R console prompt, I also have to enter the “stage” value. Whatever I put in there, I get an error.
