Re: iTunes Local Control and Catalina

That's very weird. The plugin compiles all the applescript objects on startup. In your case it looks like it's successfully compiling the first 9 objects and choking on the 10th.

My only suggestion at this point is to delete the plugin entirely and reinstall a fresh copy. If that doesn't work, we may need Matt or Jay to help dig into why the applescript compiler inside IndigoPluginHost is failing.

Ok, I've tried this (plugin disabled/deleted and installed a new copy) and still doesn't work.

Re: iTunes Local Control and Catalina

We're using a library, so I don't know for sure what's going on. I wonder if there's something odd in the names of stuff that might be causing an error? I don't recall how the plugin works but if it's just failing on one instance then I'd suspect that something is odd about that instance.

Re: iTunes Local Control and Catalina

It's working for other users, so it must be something peculiar to this one system, I should think.

Based on the line numbers, the source sent to applescript.AppleScript() should be:
Code: Select all
on run(args)
    tell application "iTunes" -- or "Music" depending on OS version
        next track
    end tell
end run

I can add some debug logging for yassi to confirm that it's successfully compiling the previous applescript objects and failing on the one above. But beyond that, I haven't a clue.

It'll be a day or two to get it posted.

FWIW, I am seeing the same error message:

Re: iTunes Local Control and Catalina

I believe the problem is this version check:

Code: Select all
mac_base_ver = int(os.popen("sw_vers -productVersion").read().strip().split(".")[0])
if mac_base_ver > 10:
    AS_TARGET_NAME = "Music"
else:
    AS_TARGET_NAME = "iTunes"


I am on Catalina 10.15.7 using the Music.app. The plugin loads fine if I hard code AS_TARGET_NAME to "Music". I suspect the check works fine in Big Sur as well.

Re: iTunes Local Control and Catalina

So the version check should be this instead?:
Code: Select all
mac_base_ver = int(os.popen("sw_vers -productVersion").read().strip().split(".")[0])
if mac_base_ver >= 10:
    AS_TARGET_NAME = "Music"
else:
    AS_TARGET_NAME = "iTunes"

I have a High Sierra machine and a Big Sur machine and had check the internet for which OS version switched to Music.app. Not surprised if I got it wrong by one.

Could you test this change and confirm? Thanks.

Re: iTunes Local Control and Catalina

Where do I have to change this? Which file?
