Can't find module in unit tests

[quentinncl]

I'm using this package with envelop and apollo-server-express. When I'm runing my server, it works well that perfect.

But when I'm running my unit tests I have the following error : "Cannot find module 'graphql-ws/use/ws' from <my_js_file>"

I tried :

• to configure my jest config adding graphql-ws in the moduleNameMapper
  "^graphql-ws$": "<rootDir>/node_modules/graphql-ws/use/ws" but does not work.
• To remove node_modules from the testPathIgnorePatterns and modulePathIgnorePatterns too but does not work.

I had to comme back to version 5.16.2 and in this case it works.

Is there anyone had this error ?

You're mapping to the an incorrect location.

- "^graphql-ws$": "<rootDir>/node_modules/graphql-ws/use/ws"
+ "^graphql-ws$": "<rootDir>/node_modules/graphql-ws/dist/use/ws"

BTW, why do you even need the module name mapper?

Oh I'll try ! thanks !

It was an idea because of my error in my unit tests I tried this way :)
