Answer 1 · 2019-11-11T20:15:13.000Z

I'm unable to reproduce this unfortunately. It seems that this occurs when devices contains an item that is None, though that results in a different, though similar error ('NoneType' object has no attribute '__getitem__').
Could you try the following commands, in order to clean up your workflow cache / data dir?

blt workflow:delcache
blt workflow:deldata
blt workflow:delsettings

No worries, there's no preferences persisted, only some caching going on here. If this has no effect for you, could you share the result of blueutil? You can execute a blueutil command by doing the following:

Open the Bluetooth Connector workflow in alfred, right click and open in terminal.
Run ./blueutil --paired --format JSON | pbcopy in that directory
Post the results here

Answer 2 · 2019-11-12T08:56:25.000Z

The command don't seem to help.
Here you are (I just stripped the MAC addresses)
blueutil --paired --format JSON | jq '(.[] | .address) |= "aa-bb-cc-dd-ee-ff"' | pbcopy

Answer 3 · 2019-11-12T09:14:09.000Z

I'm wondering if the "device" with null name could be the culprit.

Answer 4 · 2019-11-12T21:26:02.000Z

Hi @lubosek, thanks for the issue and the output json. It is probably the same or similar issue than this comment. It definitely would make sense to filter devices with a null name. Can you try this version: Bluetooth Connector.alfredworkflow.zip ?

Answer 5 · 2019-11-13T09:26:09.000Z

Works fine now.
Thank you for fixing the bug and for the workflow in general!

Answer 6 · 2019-11-13T21:36:00.000Z

Great to hear this fixes it @lubosek :) Just published version 0.8.0.

If you have a PayPal, I'll buy you a beer!

That's very kind, but none required. ;)
