Underscore at the beginning of internal SPO column name / "search" filter query?

I'm trying to use a filtered "Get Items" step to pull up a list of SPO list queries in a certain category, but I've discovered that the internal name for the column begins with an underscore (%5F). I've tried having my entry for the "Filter query" field be:
_Category eq 'category name'
%5FCategory eq 'category name'
but both of those cause the step to fail. How do I phrase my query so that it works, or, failing there a "filter query"-friendly query that filters by rows containing a phrase?

Thank you!

Hi @beck_,


Could you please share more details about the "%5FCategory" column in a sharepoint list?

What is the type of "%5FCategory" column?


I have made a test on my side and have created a "%5FCategory" column in a sharepoint list with Single line of text type.


You could refer to screenshot below to create the flow:



The expression in the Filter Array field as below:

OData__x0025_5FCategory eq 'a'


The flow would run successfully as below:



Best regards,




Hello Alice,


The column type is also a single line of text. However, when I ran the query that you provided (with a replaced with the desired value), the Flow returned a 400 error, with the following detail:

Column 'OData__x0025_5FCategory' does not exist. It may have been deleted by another user.


Trying the query without OData  or OData_ returns the same error.
