Just want to give my take on what was the root cause of this issue for me.

We have an Angular2 app, that is calling our NodeJS REST api. The rest API then calls another service (SOAP I believe).

We found out that our SOAP service did not have the endpoint(?) in only one environment (worked everywhere else). When the NodeJS api was calling the SOAP service, the soap service was returning an error saying 'X is not a function'. When the error response was returned to NodeJS, it did not have the proper error/exception handling, so it was completely killing the service. Thus, the UI was not getting a response.
