I’ve been trying to figure out this series of errors for awhile now and the errors in the docs are just _incredibly unhelpful_ with how vague they are.
Here’s my code (I’m using NodeJS):
function handleOAuthRedirectRequest (req, res) {
let {code} = req.query
axios.post(`https://www.patreon.com/api/oauth2/token?code=${code}&grant_type=authorization_code&client_id=${patreonId}&client_secret=${patreonSecret}&redirect_uri=${redirect}`, {}, {headers: {‘Content-Type’: ‘application/x-www-form-urlencoded’}})
.then(result =\> console.log(result))
.catch(e=\>console.log(e))
}
And I’m getting a 401 { error: ‘invalid\_grant’ }.
When I change it to …&grant\_type=\_code&client\_id…
I get 400 { error: ‘unsupported\_grant\_type’ }
I’ve also tried pushing everything through in the body and that didn’t work either.
What do these errors mean? What am I doing wrong?

Peculiar! I don’t see any issue on first glance.
In the 401 response, there should a request id. Can you send that our way, so we can look into the request to see more details around what’s going on?

It is.
So, the error isn’t a 401 - it’s 400, so there’s something about the request that’s bad but I’m not sure what it is and both errors I’m getting aren’t helpful

So you’re saying this one is actually a 400? Is there a request id in the response body?

Yeah, that’s correct - I mistyped and it should be 400.
Are you talking about what’s underlined in red here:
Because the body of the response object I’m getting back only has data: {error: ‘unsopported\_grant\_type’}

Nothing yet, huh? Must be quite an issue to take more than 2 weeks to fix
