error from node js server but doesnt point to any specific file

  • I have one api one domain and all the other apis in other domain.
  • so in SprtsAppConstatnts.js I have hard coded all the domains.
  • when I print then formatUrl ---> which is present in document.js it prints which is the correct domain then formatUrl ---> http://players.com/run/kit/?id=090000000009009093292390230923
  • where as one present in URL ===> in the file SportsResUtility.js prints an incorrect domain URL ===> http://sports.com/tes/run/kit/?id=090000000009009093292390230923
  • since it taks the hard coded value exports.DATA_DNS_NAME = "http://sports.com"; from the file SprtsAppConstatnts.js
  • not sure how to add a codition in SportsResUtility.js so that for this path alone it should add this domain http://players.com
  • I am getting two erros which I have showed in the server logs.Not sure from which file its coming. (node:30332) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Can't set headers after they are sent. (node:30332) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
  • Is there any way to findout from which file its coming. Do I need to install any other packages for debugging.
  • Providing my code snippet and sandbox below

Solution

  • (node:30332) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Can't set headers after they are sent.

    This error means that you make send() on request and then try to work with it like it is not send yet and send again.

    You pass you variable res to SportsResUtility.callService where you call res.send() and also you call res.send() in document.js, so you do it twice, which is not possible.
