Cannot find module - node.js

Question

I have a class that I have created and put it in a custom folder in the src folder. It is not a nestjs module nor a provider just a helper class that I can instantiate and use. However when I run the app I got the following error:
npm run start:dev
> rent-go#1.0.0 start:dev /Users/arsenegandote/Applications/js/rent-go

This is the generic class I am instantiating in a controller:
export class JsonResult<T> {
readonly status: string;
readonly data: T;
constructor(status: string, data: T) {
this.status = status;
this.data = data;
}
}
And my controller implements this abstract class:
export abstract class ApiController {
failed(): void {
throw new HttpException(
{
status: ApiStatus.FAILED,
data: {},
},
HttpStatus.INTERNAL_SERVER_ERROR,
);
}
notFound(): void {
throw new HttpException(
{
status: HttpStatus.NOT_FOUND,
data: [],
},
HttpStatus.NOT_FOUND,
);
}
badRequest(message: string): void {
throw new HttpException(
{
status: HttpStatus.BAD_REQUEST,
data: {
message,
},
},
HttpStatus.BAD_REQUEST,
);
}
success<T>(data: T): JsonResult<T> {
return new JsonResult<T>(ApiStatus.SUCCESS, data);
}
}

Error: Cannot find module './json.result.js'
The error means that your file cannot be found. Make sure your import path is correct.
