Get file property from a share point document list using flow


I need to populate a gallery with some file property (only the name), filtered from a share point document list structured with several sub-folders.

The flow is triggered by a power apps button, with this on select  istruction:

Set (MyOutput; test_query.Run().result)

The varible MyOutput is the text of a textbox, where I'd like to see the result

 I realized the following flow sequence:


  •  PowerApp (button trigger)
  • Get File Properties
  • Array filter (file name that start with a string)
  • Initialization of an array variable( called Column)
  • For Each cicle
    • Select (to select only the name field)
    • Append the Column variable
  • Join (to obtain a single String with all the filtered names separated by "*"
  • Respond to Powerapps (Result variable as output)



These are the details:





I tested the flow and it is OK but my textbox remains empty (i'm sure that files with searched name exist)

I've the suspect that the problem is in the array filter or in the selection but I'm not able to go over.

Thanks in advance for your contribute.
