backend_nestjs    | [Nest] 373  - 04/11/2023, 3:07:21 PM   ERROR [ExceptionHandler] Nest can't resolve dependencies of the ChatGateway (ChatService, PrismaClient, ?). Please make sure that the argument UserService at index [2] is available in the ChatModule context.
backend_nestjs    | 
backend_nestjs    | Potential solutions:
backend_nestjs    | - Is ChatModule a valid NestJS module?
backend_nestjs    | - If UserService is a provider, is it part of the current ChatModule?
backend_nestjs    | - If UserService is exported from a separate @Module, is that module imported within ChatModule?
backend_nestjs    |   @Module({
backend_nestjs    |     imports: [ /* the Module containing UserService */ ]
backend_nestjs    |   })
