Nest can't resolve dependencies of the JwtService (?). Please make sure that the argument JWT_MODULE_OPTIONS at index [0] is available in the JwtModule context.

I'm receiving the error in the title and nothing I got from searching the internet helped.
These are the relevant parts of my code:

import { Injectable } from '@nestjs/common';
import { JwtService } from '@nestjs/jwt';
import { ForbiddenException } from '@nestjs/common';

@Injectable()
export class TokenService {
  constructor(private readonly jwt: JwtService) {}

  async sign(payload: object) {
    return this.jwt.sign({ payload });
  }

  async verify(token: string) {
    try {
      const { payload } = this.jwt.verify(token);
      return payload;
    } catch (exc) {
      throw new ForbiddenException();
    }
  }
}

import { Module } from '@nestjs/common'
import { TokenService } from './token.service'
import { ConfigModule, ConfigService } from '@nestjs/config'
import { JwtModule } from '@nestjs/jwt'

@Module({
  providers: [TokenService],
  imports: [
    JwtModule.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (config: ConfigService) => ({
        secret: config.get<string>('SECRET'),
      }),
    }),
  ],
  exports: [TokenService],
})
export class TokenModule {}

import { Module } from '@nestjs/common'
import { AppController } from './app.controller'
import { AppService } from './app.service'
import { TokenModule } from './token/token.module'
import { AuthModule } from './auth/auth.module'
import { ProfileModule } from './profile/profile.module'
import { MongooseModule } from '@nestjs/mongoose'
import { ConfigModule, ConfigService } from '@nestjs/config'
import { JwtModule } from '@nestjs/jwt'

@Module({
  imports: [
    MongooseModule.forRoot('mongodb://localhost/db-name'),
    ConfigModule.forRoot(),
    JwtModule,
    TokenModule,
    AuthModule,
    ProfileModule,
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}
