Help with Schedule API (adding results to a thing not working)

[letsexecute]

EDIT 1: So I was able to make it partially work. But it now only adds 1 payment to its project. Please, scroll down to the bottom of this post.

EDIT 2: It wasn’t really adding only one payment. But a random number lower than the amount it should be creating. So I experimented with adding an interval:

here’s how I’ve set up the make changes to a thing. Is this correct?

Thanks!

Ok, so here’s my workaround, since the reliability of this whole Schedule API isn’t good.

I’ve created a custom event that searches for all payments with the cosntraint of project = This project:

Then I added a delay for triggering this event:

What do you guys think?
