I am querying all files from a given folder in Power Automate. I have used the below in the filter query of Get Items action:

    {FullPath} eq 'GSD Test Document Library/DS0001'

But while running the flow, getting the below error:

**The $filter expression "{FullPath} eq 'GSD Test Document Library/DS0001'" is not valid. Creating query failed.** 

What is invalid in the filter query?

Note: I don't want to use the REST API, want to get using SharePoint action.
