TypeScript error Object is possibly 'undefined'

[montogeek]

When using an authenticationModule, and "strict": true in the TypeScript configuration, the compiled routes.ts throws a TypeScript error: Object is possibly 'undefined' on line 519:

By setting "strictNullChecks": false the error goes away.

Expected Behavior

No errors in the routes.ts file.

Current Behavior

Object is possibly 'undefined'

Possible Solution

• A fix would be to somehow tell TypeScript that the import is actually defined.
• Another option is to check for it in the Handlebars template:

  if(expressAuthentication != null) {
  secMethodAndPromises.push(
                          expressAuthentication(request, name, secMethod[name])
                              .catch(pushAndRethrow)
                      );
  }

Steps to Reproduce

1. Define an authenticationModule.
2. Export an expressAuthentication function.
3. Compile routes.ts file with tsoa spec-and-routes
4. See TypeScript error when running the express app.

Context (Environment)

Version of the library: 6.0.1 Version of NodeJS: Node 20.10.0

My bad, the expressAuthentication was returning undefined too, carry on!
