Describe the problem/error/question
Hello good people, I need to filter out items where the amount is empty (null). I tried to use Filter which is working when manually triggered with the Test step button inside the node. But when I hit the Test workflow button I get an error - “Wrong type: ‘NaN’ is a number but was expecting a number [condition 0, item 1]” Which sounds a bit odd, doesn’t it? 
The workflow then stops.
Workaround for me was to use Filter node v1 with “Is not empty” option.
What is the error message (if any)?
I kept some data pinned. It is anonymized but should work for testing. The Filter1 is the v2 that is having issues. The Filter is v1 that currently works for me.
Wrong type: ‘NaN’ is a number but was expecting a number [condition 0, item 1]
Please share your workflow
