Reproduction steps

  1. With Vue language extension v0.3.0 installed create a new .vue file
  2. Add a basic Vue SFC scaffold for the composition API
  3. Add a new Div with an Emmet completion like ".test-class"
  4. Try to add an attribute to the Div like v-if="test"
  5. Try invoking another Emmet completion by typing '.' somewhere in the component template

Current vs. Expected behavior

Current behavior: something causes the vue-language-server to crash silently with the following errors in the LSP logs:

/Users/amxmln/Library/Application Support/Zed/extensions/work/vue/node_modules/@vue/language-service/lib/plugins/vue-template.js:604
                                ...meta?.props.map(prop => [prop.name, prop]) ?? [],
                                              ^

TypeError: Cannot read properties of undefined (reading 'map')

Node.js v24.13.0

This causes Emmet completions and other features like auto-imports, SCSS completions in the <style>-section, etc. to no longer work until the language server is manually restarted.

Expected behaviour: the vue-language-server works as intended and doesn’t silently crash.
