Error on API generation: TypeError: Cannot read properties of undefined (reading 'logger')

[NathanTe]

When I try to regenerate my api i get this error Error on API generation: TypeError: Cannot read properties of undefined (reading 'logger')

everything worked fine on ng-open-gen V23. Is this issue related to me being on Angular 14.2.10 instead of Angular 15?

~Also is it possible to skip the self-signed certficate check. Didn't find anything in the --help~

I've run into the same issue today, in a new Angular project (ng-openapi-gen v0.24.0) . Older angular projects don't have this issue (ng-openapi-gen v0.23.0)

I'll try for more information / steps to reproduce if/when I find some time.

Same error here. I'm on Angular 15.1, ng-openapi-gen v0.24.0. I will try with v0.23.0 and report back.

UPDATE: Downgraded to version v0.23.0 and everything works again

I couldn't reproduce this error... Maybe it is a combination of specific descriptors, or NodeJS version... Please, post the result of npx ng version and, if possible, a minimal descriptor to reproduce it. Thanks!

Might be a bad combination of Angular and Node. I just installed the latest of ng-openapi-gen and ran it with this json. Command line gave me the same results though.

{
    "$schema": "node_modules/ng-openapi-gen/ng-openapi-gen-schema.json",
    "input": "http://localhost:5000/swagger/v1/swagger.json",
    "output": "src/app/api",
    "ignoreUnusedModels": false
  }

It is surely a combination of versions... If you try Node 18 LTS, will it work?

I've just generated a new project with Angular (below is the output)

❯ npx ng version

And generated with the Cyclos API, which is quite large, and things just work...

npm i -D ng-openapi-gen

npx ng-openapi-gen --input https://raw.githubusercontent.com/cyclosproject/cyclos4-ui/master/src/openapi/cyclos-openapi.yaml

I tried this with

Node: 16.15.0 and ng-openapi-gen 0.24 and got the same error.

After upgrading to Node: 18.14.2 it works!

Thanks Manuel Varverde (which replied and I think, removed the post), which made me able to at least reproduce the issue. He was setting the json to a Swagger V2, not OpenAPI V3, and the error was in an early context where the logged wastn't initialized yet. I've fixed it, so, maybe you (@NathanTe, @georcon, @mode777 ) can also try to reproduce with version 0.24.1?

[mvalverdevs]

Thank you @luisfpg (I removed the post because I saw that I was using Swagger V2 version too)

I use this module to covert my Swagger V2 json api file to OpenAPI V3 yml file. And that works.
