You shouldn’t need to install anything.

 

First try this solution. If that doesn’t solve it, what’s your exact (don’t say latest) version of Alfred and macOS? Plus, please share the link to one of those workflows and the full debugger.

Hi Vitor,
I don't have such file were you said, I have only a com.apple.ScriptEditor2.LSSharedFileList.plist. that's an empty plist
I have Alfred 5.0.6, the system is Ventura 13.1
The plugin is Pause Tabs (is yours, I suppose), version 2002.2

testing on Safari with Allow JavaScript from Apple Events  enabled

thank  you!

Look for your error online. That message is coming from macOS, not Alfred. Something atypical seems to be going on with your installation, so first you need to figure out what. Maybe another app is interfering. Have you simply tried rebooting?

yes reooted, but I have noticed this problem before switching to Ventura
if in terminal I do the following:

osalang -l

I have

asDB lns  cgxerv-h  AppleScript Debugger
ascr appl cgxervdh  AppleScript
jscr appl cgxe-v-h  AppleScript
scpt appl cgxervdh  Generic Scripting System

I imagine I should see also Javascript...

 

[vitor]

Here’s mine (13.0):

 

ascr appl cgxervdh  AppleScript
jscr appl cgxe-v-h  JavaScript
scpt appl cgxervdh  Generic Scripting System

 

Something is wrong with your jscr line.

[juliosecco]

where?

thanks

[vitor]

Compare yours with mine:

 

jscr appl cgxe-v-h  AppleScript
jscr appl cgxe-v-h  JavaScript

Command not found!

I had a similar problem—after upgrading from Monterey to Ventura (13.2.1), my workflows using osascript/JavaScript all failed to run.

 

It took a bit of diagnostic and search work, but I found a simple solution. It applies only if you've installed the 3rd-party app Script Debugger. If so, try deleting the "~/Library/Components/Script Debugger.component" folder it installs. This immediately fixed the problem for me (no reboot required).
