How to make the NG Zorro modal stay opened after a promise rejection

Question

I know you can make a modal to stay opened by returning false from nzOnOK field:

this.modal.confirm({
      nzTitle: 'Do you Want to delete these items?',
      nzContent: 'When clicked the OK button, this dialog will stay opened',
      nzOnOk: async () =>{
        return false;
      }
    });

But in my case, I have a method called from a service that might return a promise rejection or not.

I would like to make the modal stay opened if the service call fails

this.modal.confirm({
      nzTitle: 'Do you Want to delete these items?',
      nzContent: 'Some content',
      nzOnOk: async () =>{
        await this.myService.someMethod(); // this throws error and it should make the modal stay open
      }
    });

Is there a config I am missing because I don't find anything in documentation that says the modal to stay open in case of promise rejection.

Also, I don't want to use try catches or temporary variables to do this since it will defy the purpose of the rejection I am using.

Answer 1

The modal should stay opened the callback is return false or Promise<false>:

Here's an example with promise:

export class MyService {
  someMethod() {
    return Promise.reject();
  }
}
...
nzOnOk: () => {
   return this.myService.someMethod().then(res => !!res).catch(() => false); 
}
