I have written a script for Spotify with a subroutine

tell application "Spotify"
    ⋮
    silentVolume(tmpDur)
    ⋮
end tell

on silentVolume(tmpDur)
    tell application "Spotify"
        ⋮
        set tmpDur to ((duration of current track) / 1000)
        ⋮
    end tell
end silentVolume

Two problems with this

  1. When I call silentVolume with a float I get an error -1708 and the error message (translated to English so this is an approximation) "Spotify encountered an error. Cannot continue silentVolume". Why?
  2. silentVolume doesn't seem to inherit the context (tell application "Spotify") of the main function. Why?

Initially this subroutine was part of the main function and then it worked fine but I needed a recursive solution, therefore I had to break it out into a separate method.

  • What's with the four occurrences of vertical dots ⋮ in the code? They do not compile! What happens if you use set tmpDur to ((duration of current track) / 1000) as integer, does it still throw an error?

  • It was just a vertical replacement for an ellipsis (…) you can use to indicate that something was left out.

  • @user3439894 It fails already on the tell-statement in the subroutine.

It was a problem with the scope. This question got me on the right way. I needed to change the call to the subroutine to

my silentVolume (tmpDur)

and then now works as expected. Leave it here as a future reference for anyone googling error -1708.
