JSON Decoder error

[miguelcarcamov]

Hi,
From some days ago I have been receiving an error after running razer-cli -e multicolor,xpalette --sync.
The error that shows up is:

Traceback (most recent call last):

I'm trying to debug the error without any success. I'm on Manjaro Linux x86_64 with kernel 6.5.0-1-MANJARO

I was having the same issue with the same error message and it was because of an extra ] at the end of ~/.cache/razer-cli/razer-cli-settings.json. I removed it and everything works fine, I've been unable to find a way to reproduce that issue so I'm not sure what caused it. I tried running python /usr/lib/python3.13/site-packages/razer_cli/tests/test_util.py and one of those tests fails which seems to be related to writing to that file. Both removing the problematic bracket and just deleting the json file worked in solving it for me. So rm ~/.cache/razer-cli/* is a quick and easy fix for it.

So maybe there's something wrong there but I've not seen any issues in using razer-cli since I removed that bracket. And I tried reinstalling to see if it was just a problem when it was freshly installed but I didn't have issues there either.

Closing as heisenbug with usable workaround, re-open if it appears again.👌
