Redis - The client is closed - caching

Question

I want to save a token in the redis cache after user sign-in in my app.
The cache config.service.ts file:
#Injectable()
export class CacheConfigService {
constructor(private configService: ConfigService) {}
get url(): string {
console.log(this.configService.get<string>('redis.url'));
return this.configService.get<string>('redis.url') as string;
}
}
The cacheModule file:
#Module({
imports: [
CacheModule.register<RedisClientOptions>({
// #ts-ignore
store: createRedisStore,
socket: {
host: 'localhost',
port: 6379,
},
isGlobal: true,
// url: 'redis://' + process.env.REDIS_HOST + ':' + process.env.REDIS_PORT,
}),
],
})
The user signin method:
emailPasswordSignInPOST: async (input: any) => {
if (
originalImplementation.emailPasswordSignInPOST === undefined
) {
throw Error('Should never come here');
}
let response: any =
await originalImplementation.emailPasswordSignInPOST(input);
const formFields: any = input.formFields;
const inputObject: any = {};
for (let index = 0; index < formFields.length; index++) {
const element = formFields[index];
inputObject[element.id] = element.value;
}
const { email } = inputObject;
const user = await this.userService.findOneByEmail(email);
const id = user?.id;
const payload = { email, id };
const secret = 'mysecret';
const token = jwt.sign(payload, secret, {
expiresIn: '2h',
});
response.token = token;
const cacheKey = 'Token';
await this.redisClient.set(cacheKey, token, {
EX: 60 * 60 * 24,
});
return response;
},
Please note that this is a different module.
When I send signin request from postman than it logs this error in the console: "Error: The client is closed"
I ran the app with the command DEBUG=* npm run start:dev to see the logs about redis but there is no log about redis.
