Issue with @ewsjs/xhr and ews-javascript-api cann't read property of undefined

[MahmoudShaltoot]

Hello!
I am trying to initialize calender folder object using ews.CalendarFolder.Bind(exch, ews.WellKnownFolderName.Calendar) but I get this error

TypeError: Cannot read properties of undefined (reading 'headers')
    at NtlmProvider.preCall (D:\TDRA\tra-gate-api\node_modules\@ewsjs\xhr\dist\ntlmProvider.js:48:27)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async XhrApi.xhr (D:\TDRA\tra-gate-api\node_modules\@ewsjs\xhr\dist\xhrApi.js:123:25

Here is the code

      // create instance
      let xhr = new XhrApi({rejectUnauthorized: false})
        .useNtlmAuthentication(credentials.userName, credentials.password);

      ews.ConfigurationApi.ConfigureXHR(xhr);

      var service = new ews.ExchangeService(ews.ExchangeVersion.Exchange2013);
      service.Credentials = new ews.WebCredentials(credentials.userName, credentials.password);
      service.Url = new ews.Uri(this.app.options['exchangeServiceUrl']);
      service.ImpersonatedUserId = new ews.ImpersonatedUserId(ews.ConnectingIdType.SmtpAddress, email)

      // Initialize the calendar folder object with only the folder ID.
      let calendar = await ews.CalendarFolder.Bind(service, ews.WellKnownFolderName.Calendar);
      ...

This issue occurs with ews.CalendarFolder.Bind(service, ews.WellKnownFolderName.Calendar);

PS: I tried to figure out what is the issue from the package I found that this request returns undefined

can you find out why err.response is undefined or would it be undefined all the time.

Hii @gautamsi, I found that there is a connectivity issue with exchange server, Axios throws an error with a message connect ETIMEDOUT 185.54.18.22:443

AxiosError: connect ETIMEDOUT 185.54.18.22:443 at AxiosError.from (D:\TDRA\tra-gate-api\node_modules\axios\dist\node\axios.cjs:836:14) at ClientRequest.handleRequestError (D:\TDRA\tra-gate-api\node_modules\axios\dist\node\axios.cjs:3086:25) at ClientRequest.emit (node:events:514:28) at TLSSocket.socketErrorListener (node:_http_client:501:9) at TLSSocket.emit (node:events:514:28) at emitErrorNT (node:internal/streams/destroy:151:8) at emitErrorCloseNT (node:internal/streams/destroy:116:3) at process.processTicksAndRejections (node:internal/process/task_queues:82:21) at Axios.request (D:\TDRA\tra-gate-api\node_modules\axios\dist\node\axios.cjs:3876:41) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async NtlmProvider.preCall (D:\TDRA\tra-gate-api\node_modules\@ewsjs\xhr\dist\ntlmProvider.js:43:30) at async XhrApi.xhr (D:\TDRA\tra-gate-api\node_modules\@ewsjs\xhr\dist\xhrApi.js:123:25) { port: 443, address: '185.54.18.22', syscall: 'connect', code: 'ETIMEDOUT', errno: -4039, ...

Can we throw an error here?

Thank you for your help.

I've had the lib throw the same error on two production environments so far. It's still unclear why response is undefined in their cases, but it happened. I'll try to patch the lib to try to collect some more useful log to see if I can identify what is arriving as response.
