Hey @Nick_Milner,
thank you for your feedback 
It is my first workflow, but I really want to make it work for everyone. Maybe you can help me out finding whats wrong.
Can you tell me where you found my Mac username? The BundleID is just a unique name that will be converted to an ID (as far as I know right now), so this can stay the same.
Also inside the script, there is $coda = new \danielstieber\CodAlfred\CodAlfred($key); which should not be altered! This is the PHP namespace, where the script finds the function in the class, that handles all operations. If you change this, the script should definitely stop working 
On the top right corner of the workflow page should be a little bug icon. If you click it, the debug console opens. If you now open alfred with you shortcut and use the workflow, you should get feedback there. So e.g. if you put in ‘cd asdf’ and it does not work, you should theoretically get an error there. Can you maybe look, if an error pops up?
