AppleScript - relinking file in Indesign - Cannot create the link resource from the given URI

Question

I am trying to make a Folder action in Automator, which duplicates specific .indd file, opens it in InDesign and then relinks "test1.png" with a file that was dropped in the folder, which is bound to the Automator action.

I can get it working with hardcoded file path, but if I try getting the file path dynamically it gives me error "Cannot create the link resource from the given URI"

It's probably something very simple, but I am new to AppleScript and can't figure it out.

Code:

on run {input, parameters}

tell application "Finder"
    set filename to name of file input
end tell

tell application "Adobe InDesign 2020"
    if document 1 exists then
        tell document 1
            relink link "test1.png" to "Macintosh HD" & filename
            
            try
                update link "test1.png"
            end try
            
        end tell
    end if
end tell

return input

end run

I don't have Adobe InDesign to be able to test this but try this.

on run {input, parameters}

set theFile to input's item 1

tell application "Adobe InDesign 2020"
    if document 1 exists then
        tell document 1
            relink link "test1.png" to theFile
            try
                update link "test1.png"
            end try
        end tell
    end if
end tell

end run
