QueryString instead of FormData

[jlee0425]

Hi,

I am having trouble integrating Kakao Login in my build with Next-Auth.
Everything seems to go through normally and I asked Kakao about not getting any information back except 'invalid_client (Bad client credentials)' Error but they say there has been no logs regarding my auth error.

It seems that the problem might be that Kakao only accepts Query String but instead I think I am sending data as FormData.

Their doc also specifies to send the data in application/x-www-form-urlencoded also. I'm confused and I would like to try sending it in QS if possible.

Any help would be appreciated greatly.

// api/auth/[...nextauth].ts
KakaoProvider({
    clientId: process.env.KAKAO_API_KEY,
    clientSecret: process.env.KAKAO_CLIENT_SECRET,
    authorization: {
      params: {
        response_type: 'code',
        scope: 'profile account_email gender age_range phone_number',
        redirect_uri: 'http://localhost:3000/api/auth/callback/kakao',
     },
   },
}),

// from Kakao Documentation for getting authorization token
Request
https://kauth.kakao.com/oauth/authorize?response_type=code&client_id={REST_API_KEY}&redirect_uri={REDIRECT_URI}


// The way I am requesting 

Payload -> FormData
csrfToken: some token
callbackUrl: some URL
json: true
