yes!
that was the problem
my apologies I missed these arguments in the request URLhowever,
i am now getting the error{error: 'invalid_grant', error_description: 'invalid code verifier'}The URL includes both code_challenge and code_challenge_method
and looks like:https://www.dropbox.com/oauth2/authorize?response_type=code&client_id=<client_id>&code_challenge=<code_challenge>&code_challenge_method=S256
and the parameters sent to oauth2/token are:client_id=<client_id>&grant_type=authorization_code&code=<auth code from dropbox>&code_verifier=<128 char verifier>i also made sure that <code challenge> is a SHA256 hash of <128 char verifier> by testing it at https://emn178.github.io/online-tools/sha256.html
what am i missing?
