The following value is not valid for the runtime prompt

Hello everyone,

I am facing with stupid error.

I have a ruleset and attached it to the form for running after save.

However, when I clicked on the Save button, the runtime prompt appeared, and I could not run the rule with the error

The following value is not valid for the runtime prompt: FY27.

When I go to the Rules screen and run with the same prompt, it runs successfully:

I really don't know why it happens. I tested this a few days ago on the form , and it ran perfectly; however, today, when re-testing, it failed.

What should I do in this case?
