Passport JwtStrategy never executed in nestjs - nestjs

Question

I am using nestjs and having an issue with using guards to authenticate a request.
My JwtStrategy is never execute.
Here is my JwtStrategy :
#Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
constructor(
#Inject('IQueryBusAdapter')
private readonly queryBus: IQueryBusAdapter,
) {
super({
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
secretOrKey: process.env.JWT_SECRET_KEY,
});
}
validate = async (payload: IJwtPayload) => {
Logger.log('INNNNN');
const query = new GetUserByIdQuery();
query.id = payload.id;
const user = await this.queryBus.execute(query);
if (!(user instanceof User)) {
throw new UnauthorizedException();
}
return user;
};
}
I also try to call directly validate() directly in constructor but nothing change...
My AuthModule :
#Module({
imports: [
BusModule,
JwtModule.register({
secretOrPrivateKey: process.env.JWT_SECRET_KEY,
signOptions: {
expiresIn: process.env.JWT_EXPIRES,
},
}),
PassportModule.register({ defaultStrategy: 'jwt' }),
TypeOrmModule.forFeature([User]),
],
controllers: [RegisterAction, LoginAction],
providers: [
JwtStrategy,
],
})
export class AuthModule {}
My controller
#Get('/:id')
#ApiOperation({ title: 'Get user ressource' })
#UseGuards(AuthGuard('jwt'))
async index(#Param() query: GetUserByIdQuery): Promise<object> {
const user = await this.queryBus.execute(query);
if (!(user instanceof User)) {
throw new NotFoundException();
}
return {
id: user.id,
fullName: user.getFullName(),
email: user.email
};
}
I always received 401 status code.
Thanks for your help.

validate will only be called when you pass a valid jwt token. When the token is signed with a different secret or is expired, validate will never be called. Make sure you have a valid token. You can check your token with the jwt debugger.
