Functions did not deploy properly

I am a bit new in cloud functions stuff and trying to deploy my website on firebase but getting this error while deploying cloud functions.

!  functions[sendMail(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Error: please examine your function logs to see the error cause: https://cloud.google.com/functions/docs/monitoring/logging#viewing_logs
!  functions[app(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Error: please examine your function logs to see the error cause: https://cloud.google.com/functions/docs/monitoring/logging#viewing_logs
Error: Functions did not deploy properly.

these functions are working fine on localhost as well
