Getting Invalid Access token error recently on working code

Hi, Recently, One of my lambda function has stopped working where I was fetching cloud recording from my zoom account and feeding it to my DB.

function someFunction() {
  let Arr_Key = APIKey.split("|");
  let Arr_secretkey = APISecret.split("|");
  for (let i = 0; i < Arr_Key.length; i++) {
    const payload = {
      iss: Arr_Key[i],
      exp: ((new Date()).getTime() + 15000)
    };
    const token = jwt.sign(payload, Arr_secretkey[i]);
    const config = {
      headers: {
        "Authorization": "Bearer " + token,
        'User-Agent': 'Zoom-api-Jwt-Request',
        'content-type': 'application/json'
      }
    }
    axios.get(Zoom_End_Point, config)
      .then(async function (response) {
        let data = {};
        let Empty_arr = [];
        let recordings = response.data.meetings;
        if (!recordings || !Object.keys(recordings).length) {
          data = {
            secretKey: adminSecretKey,
            response: Empty_arr,
            ids: Empty_arr
          };
        }
        else {
          let { meetingIds, requiredMeetings, meetingAgendas } = await getDesiredRecordings(recordings,config);
          modifyMeetings(requiredMeetings, token);
          data = {
            secretKey: adminSecretKey,
            response: requiredMeetings,
            ids: meetingIds,
            agendas: meetingAgendas
          };
        }
        try {
          const res = await axios.post(Insert_API_End_Point, data);
          return {
            statusCode: 200,
            body: res
          };
        } catch (e) {
          return {
            statusCode: 400,
            body: JSON.stringify(e)
          };
        }
      })
      .catch(function (error) {
         console.log(error)                //Flow coming here
        return {
          statusCode: 400,
          body: JSON.stringify(error)
        }
      })
  }
}

In API key I have Three keys seperated with | API_key=oVxxxxx…|l4xxx…|7Xxxx…
same with Api secret key.
I’m getting error 401 with data: { code: 124, message: ‘Invalid access token.’ }
Has something changed in zoom recently? why is my function throwing error in past few days where as it was working fine earlier.

Hi @Harshal123
Was this function working previously?
Did you change any settings in your account?
