Failed: Error: 'Execute an Action on a Set of Rows'

[RazvanS]

Hello everyone,

I have a bot that is updating the data of some rows based on what was submitted via a form.

Everything worked so far, but recently after adding a few more things to the app, the update part stopped working.
I am getting the following error when executing an action from the test part of the automation bot:
"Failed: Error: 'Execute an Action on a Set of Rows' Data action 'Update Contor' for table 'Form_Data failed with exception Cannot get key values when Parent or ChangeImage are null."
Here's the code seen in the app:

I had this issue in the past with a different app, but I don't remember if I did something to fix it or was fixed by itself.

Do you have any idea what can cause this error?

Let me know if you need to see any of my actions or tables.

Thanks in advance!
