Azure Ad B2C, AADSTS9002313: Invalid request. Request is malformed or invalid

Question

As the title says, I have a problem get the access token back from the token API, I also tried using the method provided by the msal/node library.

I noticed something weird about the code I get from the redirect uri I provided, In the url I get client_info and not code image -

Im trying 3 different methods to fetch the tokens.

In the first one I get the error included in the title, in the other two I get the following error - ServerError: invalid_grant: undefined - [undefined]: AADB2C90090: The provided JWE is not a valid 5 segment token

My Code -

const getAuthentication = (azureConfig, azureAuthCode, confidentialClientApplication) => {
   //prepare the request for authentication    
   debugger    
   tokenRequest.code = azureAuthCode
   tokenRequest.grant_type = 'authorization_code';
   tokenRequest.scope = [`${azureConfig.b2c._scopes.ScheduleAppointments}`];
   tokenRequest.client_id = process.env.APP_CLIENT_ID;
   tokenRequest.client_secret = process.env.APP_CLIENT_SECRET,
   

   console.log(tokenRequest)
