Error while executing App server script!

server.js:

 uploadFromS3File: async function (options) {
    try {
     let docId = options.url.split('.com')[1]
     console.log("DOCUMENT URL: ", options.iparams.freshSalesUrl+"/crm/sales"+docId    )

      var freshsalesOptions = {
        url: "https://"+options.iparams.freshSalesUrl+"/crm/sales"+docId,
        method: "GET",
        headers: {
          Authorization: "Token token=" + options.iparams.freshsalesTokenValue,
          Accept:"*/*"
        },
        encoding: null
      };
      await request(freshsalesOptions, (err, res, body) => { 
        console.log("S3 File res: ",JSON.stringify(res), "  Body: ", JSON.stringify(body));
        renderData(null, { s3FileStatus: 200, response: body });
      
    })
   } catch (err) {
        const responseJson = { status: "error", message:err.message };
        console.log("Error in fetching S3 File:", err ? `${err.response ? JSON.stringify(err.response) : null} : ${err.message || null}` : null);
        renderData(null, { s3FileStatus: 400, response: responseJson });
    }
},```

model.js

async function invokeUpload(options) {
 return await data.request.invoke("uploadFromS3File", options).then(function (data) {
    console.log("uploadFromS3File response", data);
    return data
}).catch( function(err){
   console.log("Error In uploadFromS3File", err);
   invokeDealPayload(`Error In uploadFromS3File: ${(JSON.stringify(err))}`,`Deal ID : ${dealDataValue['DealID']}`,` Error Remarks`);
   return null
});
