subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): Subscription;

Question

I was following the tutorial but I get this error. https://docs.abp.io/en/abp/latest/Tutorials/Part-3?UI=NG&DB=EF

subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): Subscription;

An argument for 'error' was not provided.

Actually, I couldn't find where did I make mistake. Can anyone help me about this one?

This error Message popping up when mouse over on subscribe:

Answer 1

request.subscribe({
  next: (response) => {
    // treat recieved data
  },
  error: (error) => {
    // treat error
  },
  complete: () => {
    // define on request complete logic
    // 'complete' is not the same as 'finalize'!!
    // this logic will not be executed if error is fired
  }
})
