Get Files (properties only) - filter query

[Displaced_2000]

Hi

I'm not sure if what im seeing in my flow is correct or if it is an error.

I'm using get files (properties only) to retrieve properties for all files in a library.  I'm trying to limit this to files that are missing data, so I'm using the filter query 

Reference eq 'null'

Reference is a column I have created, but none of my columns that i have created actually show up in the select an item drop down. 

The only options that appear are ID, Title, CODE, Compliance, Modified, Created.  So I've just typed in Reference.

Is it correct that none of my columns are showing as options in the filter query dropdowns

Hi @Displaced_2000 

You're right. None of the columns will show up in the Filter query expression. In your case, try the following:

Reference eq null

(no single or double quotes surrounding null).

Hope it helps!
