Error executing lua on ErrorLensTelescope

[Geertsky]

Hello!
I'm encountering a problem I cannot seem to debug... Could you please have a look?
When I issue :ErrorLensTelescope I get the following error:

E5108: Error executing lua ...e/nvim/lazy/error-lens.nvim/lua/error-lens/telescope.lua:45: attempt to index local 'sign_info' (a nil value)
