Local oauth2/token endpoint returns missing grant_type error

josh.dura

I am getting the following error when trying to hit the /oauth2/token endpoint with the code given from the authorize redirect:

{
      error: 'invalid_request',
      error_description: 'The request is missing a required parameter: grant_type',
      error_reason: 'missing_grant_type'
}

Below is the data I am passing through in the POST call (redacted secret of course):

{
    "client_id":"<redacted>",
    "client_secret":"<redacted>",
    "code":"_IGmWdtvD400g5Gq9t8kkyMzgurk2YZJecB-Jf7XX1E",
    "grant_type":"authorization_code",
    "redirect_uri":"http://localhost:5173"
}

As far as I can tell, I am passing everything through correctly. I have tried enabling debug mode on the application in the local docker compose container, but I never see any event logs coming through. Any suggestions?

Hi @josh-dura -

Is this still an open issue for you? The event logs are stored in the DB, so you should be able to access them by navigating in the admin UI ( system > events log ) to get a better idea of what might be occurring.

Thanks,
Josh

@joshua Nope, was able to figure it out. I was sending the request body in JSON format instead of form URL encoded. Sorry for the late response here!
