Error 45003, Wrong client ID given, invalid_client

Question and Answers

I’m submitting a request to get a grant, but it’s not working. I have an account created after migrating from version V2 to version V3. If I try this with a test account, everything works.


        const response = await fetch('https://api.us.nylas.com/v3/connect/token', {
          method: 'POST',
          headers: {
            'Content-Type': 'application/json',
            Authorization: `Basic ${config.NylasApiKey}`,
          },
          body: JSON.stringify({
            client_id: `${config.NylasIdClient}`,
            client_secret: `${config.NylasApiKey}`,
            grant_type: 'authorization_code',
            code: nylasCode,
            redirect_uri: `http://localhost:8080/choosecalendar`,
          }),
        });

        const dataConnectToken = await response.json();
        console.log(dataConnectToken, 'dataConnectToken dataConnectToken')

And I’m getting this error. What could be the reason? I don’t have an account, and there are no matches with grantId either. Please help me resolve this.
