Please help with syntax highlighting

Lezer
1

I am trying to use CM with lezer grammar for lua language (custom simplified syntax).
But syntax highlighting is not working in any trial
using CM 6.0.1, lezer grammar and generator
Console is showing this error:

index.js?02d1:1823 CodeMirror plugin crashed: TypeError: Cannot read properties of undefined (reading 'set')
    at HighlightStyle.style (index.js?5a84:233:1)

    at PluginInstance.update (index.js?02d1:1896:1)
    at new EditorView (index.js?02d1:6295:1)

editor is created from vue3 app in custom component using this code:

        mounted() {
            var view = new EditorView({
                doc: this.doc,
                extensions: [
                    edSetup,
                    syntaxHighlighting(luaHighlightStyle),
                    luaLanguage(),
                    autocompletion({ override: [(ctx) => luaCompletions(ctx, this.variables)] }),
                ],
                parent: document.getElementById(this.idComponent)!
            });

		}

edSetup is copied from basicSetup as mentioned in comment, all lines containing “highlight” are commented

Are there any 0.x @codemirror packages in your dependencies (npm ls -a)?

Are you maybe putting the editor instance in your Vue state?

Thankyou for replay

no nothing there

about editor instance - just mounted method as I wrote is there, nothing else.

if i stepping code, there is some iteration over plugins, i can try to identify, which is doing that? Or maybe you are seeing it from callstack
