[BUG] Errors in Kulala LSP: can't insert text if there's no request in the file

[igorlfs]

Description

When I try to insert text into a freshly created HTTP file (by creating a new variable instead of jumping into writing the request itself), I'm spammed with the stack below

Steps to Reproduce

1. nvim foo.http
2. Insert @FOO=/

Request

N/A
