Hello. I am unable to a create a subscription via the Pipedream API for workflows in a project. This worked prior to moving the workflows to a project. Anyone having this problem?

2

are you running a Git-backed project?

3

Yes

4

Are you trying to create a $errors subscription or a different type of subscription?

5

A different type of subscription.

6

The listening workflow subscribes to a specified channel for events emitted from another workflow.

We need to document this, but for Git-backed workflows, you can’t make these changes via the API since they won’t be serialized on the workflow. So we added native triggers for these in the UI so you can add triggers on a development branch and commit that like any other change. Can you try:

  1. Creating a new development branch in your project
  2. Add a new trigger to your workflow
  3. Select the Pipedream app, and you’ll see a trigger for Other Workflow Events and can select the source workflow.
  4. Commit those changes and you’ll see the new trigger, which creates the subscription
    Let me know if that works!

Hi,

I am trying to subscribe one of my workflows to $errors from another one of my workflows that is in a project folder. I see from reading above that I cannot use the API. However when I go to create the trigger in the UI, I do not have an “Other Workflow Events” option show up.

This is extra confusing because the workflow is currently subscribed to many other workflows and I believe this was set up using the UI. The option just no longer appears. Please advise. Thanks!

We haven’t ported over the Other Workflow Events option to the 3.0 builder. Are you able to temporarily revert to the v2 builder and create the trigger there?

To do that open your workflow in the builder, then add ?v2=1 to the end of the URL. It’ll look something like https://pipedream.com/.../build?v2=1
