Node-Soap Cannot read property 'description' of undefined - node.js

Question

I'm using node-soap in order to create a server. Tried with different wsdls files and all worked fine but this one seems a bit more complex as it points to a schema file. I started by using SOAPUI and determine if WSDL and XSD file were ok, so I've created a mock sever through SOAPUI and requests / responses were working fine there. So I've hooked it to my server using node-soap, the server starts up no problem but when I send requests it complains about parsing but I've checked it a dozen of times and it seems to be fine.
Error
TypeError: Cannot read property 'description' of undefined

Answer 1

In my case the issue was connected to self-signed certificate when mockapi service was ran on https. node-soap was tried to get .xsd file (which is pointed in wsdl) from own server. I fixed it by adding NODE_TLS_REJECT_UNAUTHORIZED=0 in env variables. Maybe it'll be helpful for somebody because I wasted a lot of time until I found the reason.

Answer 2

May be something funny with WSDL and /or SCHEMA file but by putting the schema file within the wsdl it did work for me. I understand no many companies are using SOAP but in case someone comes across this type of issue this solution might work.

Answer 3

I had the same problem; In my case the schemaLocation attribute was not pointing to a valid path, and node-soap was failing silently (!) before it could map definitions from the WSDL, which cause the error that you're seeing.
In my case I switched to a Unix-style relative path and everything was hunky-dory.
