Company: backend company-capf error "Symbol’s function definition is void: nil" with args (candidates grid-template-colum )

[khalidrafi6]

I can't use lsp completion. Whenever I type something, it says something like,

Company: An error occurred in auto-begin Company: backend company-capf error "Symbol’s function definition is void: nil" with args (candidates grid-template-colum )

I'm using html-ls.

M-x company-diag returns:
