Error in "apollo example of this repo", and also error while using "type-graphql"

[Iran-110]

After 10 changes, saving and refreshing the page, I encountered this error:

(node:26662) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 SIGTERM listeners added to [process]. MaxListeners is 10. Use emitter.setMaxListeners() to increase limit
(Use `node --trace-warnings` ... to show where the warning was created)

---

I also got this error in my local project.

In addition to this error, other errors also occur:

• My project uses type-graphql.
• At each step, by changing the content of a Resolver, the application is reset to run the server with the newer version.
• But the previous storage of reflect-metadata (belonging to "type-graphql") is not cleared.
• So, for example in my project after each reset the line below increments by 8 (the number of @Args and @Root of the file)

console.log("TypeGraphQL Functions' Param Decorators:", getMetadataStorage().params.length)
