I have a simple flow that is supposed to update a row in SQL if a field is null. I am only pulling back the ID from SQL and then looking to update records identified if one of the fields is NULL. However, it is always throwing true at the condition and updating records even if the field is NULL. I have tried using the null function and typing the word null or NULL but none of it works.

I found a post with this format but I don't know how to get a one line condition like this (I am always seeing the three fields like the snapshot above) AND I am not sure what the part in the [] is referencing (is that the field to check for null?)

How can I only update records if this field is null?
