Empty Match Table- Generate Attachment Match Table

[CatherineStanley]

I am attempting to use the Generate Attachment Match Table tool with the following parameters (I did not rename the output match table so that is the reason for the !):

When I run the tool with a Field Match Pattern of EXACT or ANY the Table is empty. (See warning below)

Below are screenshots which include a sample of the attachment files contained in the input folder and an example of the Key_Field entries.

What if we use wild card (*) in 'input data filter' or leave the parameter blank?
