In YAML files LSP completion is not happening because
yaml-language-server is failing with error:
TypeError: Cannot read properties of undefined (reading 'length')
from out/server/src/languageserver/handlers/settingsHandlers.js:78:51,
which it's expecting to have yaml.schemaStore.url.length and it's
doesn't exist.
