Infinity Item – Error message whent trying to update

Hi, I am sending data from Infinity to Crove.app with success.
During or after this „trip“ I want to send info/note back to Infinity, that the operation was already done. That means – I wnt to update particular attribute of a particular Item /it is a simple text field and I want to udate text „NO“ to „yes“.
This can be done with Zapier. I am unable to do it with Pabbly.
Here is my Workflow:

1. Infinity: Attribute value changes
   Webhook setup, tested response, all OK
2. A few date formatters /like canging date to DD.MM.YYY and so on. Tested and saved response, All OK
3. Infinity: Update item
   I choosed the exact Workspace, Board, Folder and than mapped the exact Item that caused the Trigger initially. I found that item and inserted the text „yes“ to appropriate field. However when clicked on Test response, I always get some error message
4. Create Document in Crove
   Saved, tested, OK
5. Update the Crove document (with data from Infinity Item
   Tested, Saved, OK
6. Infinity: Update Item
   Initially I had this step here, but it did not work, so I moved it to the step 4, where it does not work either

Update:
I nailed down the workflow to find where the problem is and here is another topic where I am explaining the problem:
