request undefined when extracting JWT - node.js

Question

I have followed this guide in an attempt to get JWT authentication working.
The only difference I have is that I keep JWT Token in HttpOnly cookie which means a custom extractor is required.
I found an example of how to extract a Token from a cookie. So, the only difference is:
jwtFromRequest: ExtractJwt.fromExtractors([(req: Request) => {
return req?.cookies?.access_token
}])
Unfortunately, req is undefined for no apparent reason.
That's how my auth.module.ts looks like:
#Module({
imports: [
PassportModule,
JwtModule.register({
secret: 'qweqweqweqeqwe',
signOptions: { expiresIn: '20s' }
})
],
providers: [
AuthService,
AuthResolver,
JwtAuthGuard,
JwtStrategy
]
})
export class AuthModule { }
I have also created a strategy file jwt.stragegy.ts:
#Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
constructor() {
super({
jwtFromRequest: ExtractJwt.fromExtractors([(req: Request) => {
return req?.cookies?.access_token
}]),
ignoreExpiration: false,
secretOrKey: 'qweqweqweqeqwe',
})
}
async validate(payload: any) {
return { userId: payload.sub, username: payload.username }
}
}
auth.guard.ts:
#Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {}
Could it be an error on passport.js library's side? Like, #nestjs/passport fails to map arguments or something...

Answer 1

By following the docs, you should be able to get the request.
import { ExecutionContext } from '#nestjs/common';
import { GqlExecutionContext } from '#nestjs/graphql';
#Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {
getRequest(context: ExecutionContext) {
const ctx = GqlExecutionContext.create(context);
return ctx.getContext().req;
}
}

In my scenario what was making the payload.sub undefined was the login function on auth.service.
Before (not working):
async login(user: any) {
const payload = { apiKey: user.apiKey, sub: user.userId };
const token = this.jwtService.sign(payload);
return `Access token=${token};\n HttpOnly;\n Path=/;\n Max-
Age=${this.configService.get('jwtConstants.expirationTime')}`;
}
After changes (working):
async login(user: any) {
const payload = { apiKey: user._doc.apiKey, sub: user._doc._id };
const token = this.jwtService.sign(payload);
return `Access token=${token};\n HttpOnly;\n Path=/;\n Max-Ag
e=${this.configService.get('jwtConstants.expirationTime')}`;
}
