Hey @rp_st I'm trying to use supertoken with my capacitor mobile app. I'm already using supertokens with email + password + google auth in my web version. I'm using this plugin: https://github.com/CodetrixStudio/CapacitorGoogleAuth and I used the example in https://github.com/supertokens/supertokens-react-native/blob/master/examples/with-thirdpartyemailpassword/google.js in order to make it work. I managed to get response from google auth, and to send the response to my backend, but Im allways getting the following error: "Please provide the thirdPartyId in request body". This is the request I send:

const {authentication} = await GoogleAuth.signIn();
        console.log('authentication', JSON.stringify(authentication))
        try {
          const body = {
            thirdPartyId: "google",
            oAuthTokens: {
              id_token: authentication.idToken,
              access_token: authentication.accessToken,
              refresh_token: authentication.refreshToken,
            },
            clientId: "XYZ.apps.googleusercontent.com"
          };
          const stringifyBody = JSON.stringify(body);
          console.log('stringifyBody', stringifyBody)
          let signInUpResponse = await fetch(
            `${import.meta.env.VITE_BACKEND_URL}/auth/signinup`,
            {
              method: 'post',
              body: stringifyBody,
              headers: {
                rid: "thirdpartyemailpassword"
              }
            });

          const response = await signInUpResponse.json();
          if (response.status !== "OK") {
            console.log(JSON.stringify(response))
            throw new Error("Google login failed");
          }
        } catch (e) {
          console.log(`failed with ${e}`)
        }

hey @pimpler you might wanna add content-type: application/json in the headers and try again

Hey! thank you, it was that.
