CANCEL is not caught from Promise

[tomoguisuru]

I'm probably doing something wrong but I can't seem to get a failed promise to cancel the pipeline.

pipeline__submitForm: computed(function() {
  return pipeline(this, [
    step('pipe__showLoader'),
    step('pipe__getToken'),
    step('pipe__processCharge'),
    step('pipe__showReceipt'),
  ]).onCancel(_c => this.handleCancellation(_c));
}),

pipe__getToken() {
  return stripe.createToken(card).then(response => return response.id, reason => CANCEL(reason.error.message));
}

Example using the demo Twiddle:

I hope you aren't using this addon in production, it's still very experimental.

To solve your issue, for now you need to return the cancellation token outside of the promise. I have not implemented the case where the cancellation token is returned inside of a promise. Perhaps have another step called pipe__validateToken which does that:

pipe__getToken() {
  return stripe.createToken(card).then(response => response, reason => reason);
},

pipe__validateToken(response) {
  if (response.error) {
    return CANCEL(response.error.message);
  }
  return response.id;
}

nope, not using it in prod, just trying it out. Thanks for the feedback
