onTap not working with preventDuplicates

First I want to thank you for your hard work.

I’ve used toastr with onTap from ActiveToast and every time I click on it redirects me to a different page.

this.toastrService.success('message').onTap.subscribe(() => {
  this.router.navigateByUrl('/');
});

It’s work great but when I’ve tried to block duplicate messages (preventDuplicates) I get: ERROR TypeError: Cannot read property 'onTap' of null.

Thank you!

just check if its null. I think turning on typescript’s strict mode would’ve caught this as well.

const toast = this.toastrService.success('message')
if (toast) {
  toast.onTap.subscribe(() => {
    this.router.navigateByUrl('/');
  });
}

Yeah, it looks like if ToastrService detects a duplicate message it will return null https://github.com/scttcper/ngx-toastr/blob/5829621f196c23a71a14768a935629e16bc57902/src/lib/toastr/toastr-service.ts#L179-L181
