hi, I getting this error while registering in authservice in cqrs.photos have userModel, error and authService

rough trail Dec 25, 2022, 7:40 PM

#

Why do you have a circular dependency on the command bus?

wraith patrol Dec 25, 2022, 7:49 PM

#

yes, I did exports:[CommandBus] in the userModel because of it.

rough trail Dec 25, 2022, 7:51 PM

#

But shouldn't the CommandBus be free of logic that comes from services? It should just handle calling the correct handlers, right?

wraith patrol Dec 25, 2022, 8:00 PM

#

you're right, I tried a lot and I couldn't solve the problem. How can I solve this problem exactly?

rough trail Dec 25, 2022, 8:04 PM

#

Well, first problem is that the command bus isn't a registered provider for the AuthModuke

thank you I fixed the problem. There is no problem while adding color,cars, but during auth process I get this error "statusCode":500, "message": "Internal server error". What could be the reason exactly?

rough trail Dec 25, 2022, 9:18 PM

What's in the terminal? There should be some sort of stack trace with extra error information

wraith patrol Dec 25, 2022, 9:20 PM

#

postmande does not give any error in terminal while getting this error

rough trail Dec 25, 2022, 9:21 PM

#

You just get a 500 with no error in the terminal where your server is running?

wraith patrol Dec 25, 2022, 9:23 PM

#

yes I get this not when adding color and cars but only during register

rough trail Dec 25, 2022, 9:24 PM

#

Do you have a custom exception filter being used?

wraith patrol Dec 25, 2022, 9:29 PM

#

yes there is

rough trail Dec 25, 2022, 9:35 PM

#

Well that explains why there's no log. You should probably log that error

wraith patrol Dec 25, 2022, 9:38 PM

#

I commented out the customerror in maint.ts and got the same error.How can I log error

rough trail Dec 25, 2022, 9:45 PM

#

It should be loved to the console if it's an unknown error

wraith patrol Dec 25, 2022, 9:54 PM

#

When I log the user in controller and authservis, the values come as in the photo and I get this error

rough trail Dec 25, 2022, 9:55 PM

#

What command are you trying to execute? That's a UUID, not some command class

wraith patrol Dec 25, 2022, 9:57 PM

#

my authservis is like this, I think the error comes from here

rough trail Dec 25, 2022, 10:02 PM

#

Can you show the create user command?

wraith patrol Dec 25, 2022, 10:03 PM

#

my create user metods

rough trail Dec 25, 2022, 10:08 PM

#

Do you have the command handler added to a providers array?

wraith patrol Dec 25, 2022, 10:12 PM

#

yes, there is the provider part {...UserCommandHandlers,
...UserQueryHandlers } I added it as

rough trail Dec 25, 2022, 10:12 PM

#

That's super weird. Can you provide access to the code and I'll take a look locally?

#

How am I supposed to run this without mongo?

#

Or a docker-compose so that I can run mongo in the way you expect it to be ran?

rough trail Dec 25, 2022, 11:18 PM

#

Found the issue. You're adding the CommandBus directly instead of making use of the Nest CqrsModule which adds extra setup of handling the providers. Remove any CommandBus you've added to providers arrays and instead add CqrsModule to the imports

wraith patrol Dec 25, 2022, 11:24 PM

#

I deleted CoomandBus from authmodulde providers and started getting dependency injection error. Should I use CqrsModule instead of CommandBus in AuthService?

rough trail Dec 25, 2022, 11:25 PM

#

Did you add the CqrsModule to the AuthModule's imports?

wraith patrol Dec 25, 2022, 11:40 PM

#

Thaks very much solved problem

wraith patrol Dec 26, 2022, 8:21 PM

#

hello, I can't make user.password while fetching user according to email in AuthService.private readonly userRepository: GetUserByEmailQuery and fetch with user= await this.userRepository.findOne({email}) gives a dependency injection error.My aim is to bring the user according to the mail, compare the password and perform the login process. How can I do this?

What's the error with injection?

wraith patrol Dec 26, 2022, 8:41 PM

#

this my error

rough trail Dec 26, 2022, 8:45 PM

#

Can you show the constructor of the AuthService? Looks like you're trying to inject AbstractUserRepository, which I doubt is what you're meaning to do.

#

If it is what you're meaning to do, can you also show the AuthModule so I can see the available injection tokens

wraith patrol Dec 26, 2022, 8:47 PM

#

rough trail Dec 26, 2022, 8:48 PM

#

So where does AbstractUserRepository come from?

wraith patrol Dec 26, 2022, 8:50 PM

#

AbstractUserRepository is my repository I inject it in constructor in authService

rough trail Dec 26, 2022, 8:51 PM

#

But where do you define the provider

wraith patrol Dec 26, 2022, 8:53 PM

#

I added AbstractUserRepository in UserModel in providers

rough trail Dec 26, 2022, 8:53 PM

#

What does that have to do with AuthModule

wraith patrol Dec 26, 2022, 8:55 PM

#

you are right I tried to fetch the user with GetUserByEmailQuery instead of AbstractUserRepository got passoword error

#

I get this error when using GetUserByEmailQuery instead of AbstractUserRepository.my purpose here is whether there is a user or not, to make a password check and use this method in login

rough trail Dec 26, 2022, 9:48 PM

#

So your GetUserByEmailQuery type doesn't have a password property

wraith patrol Dec 26, 2022, 9:50 PM

#

yes GetUserByEmailQuery only fetch users by mail

rough trail Dec 26, 2022, 10:04 PM

#

So typescript is telling you you can't set that property, it doesn't exist

wraith patrol Dec 26, 2022, 10:08 PM

#

yes you're right, I'm trying too, I'couldn't solve the problem

rough trail Dec 26, 2022, 10:10 PM

#

So why not use a type where you can add that property?

#

This isn't anything nest specific, this is Typescript basics

wraith patrol Dec 26, 2022, 10:44 PM

#

async validateUser(
email:string,
password:string
): Promise<LoginUserDto | null> {

const user=await this.queryBus.execute(
new GetUserByEmailQuery(email,password)
);
console.log("userrrr",user);

#

here user returns null what could be the reason

#

userrrr { user: null }

rough trail Dec 26, 2022, 11:24 PM

#

I don't think you understand what that error is telling you

wraith patrol Dec 26, 2022, 11:24 PM

#

I solved the problem

#

I am getting such an error. User comes, but user.password is undefined. What could be the reason?

rough trail Dec 26, 2022, 11:35 PM

#

Looks like you should be accessing user.user.password

#

What does the GetUserByEmailQuery command return type-wise?

wraith patrol Dec 26, 2022, 11:36 PM

#

thanks I solved proble
