ValueError: Should not happen. type: name Pops up when I insert brackets in NVIM

[5iddy]

I have encountered this error quite a few times while coding in NeoVim. It seems to popup when i try to insert parenthesis for function calls. I also have auto-pairs installed so to be specific when i press shift + 9

I dont have any other coc plugins installed in config except for python.

My coc config is directly copied from Coc readme.

I have installed Coc from the AUR and coc-python using the Coc command from inside the nvim.

I have jedi installed too, as well as jedi-vim but i had to disable it for NVIM because it was interfering with Coc.

What i have in my coc-settings.json:

{
  "python.linting.pylintEnabled": false,
  "python.linting.flake8Enabled": true,
  "python.linting.enabled": true,
  "python.autoComplete.addBrackets":true,
  "python.autoComplete.showAdvancedMembers":true,
  "python.jediEnabled":true,
}

I think i have included all the necessary information. let me know if you know anything else.

PS: its not freezing NVIM or anything like that. The error pops up and i press enter and it goes away. Nothing else seems to be broken.
