2339: Property '...' does not exist on type 'CombinedVueInstance<Vue, object, object, object, Record<never, any>>'.
Just assign a functional property.
<script> export default { functional: false, // or true ... } </script>
I'm writing Vue.js in JavaScript not in TypeScript. This error message might be for TypeScript.
But the error message appear in my editor vim with ale. And I still cannot find out which module gives me this message.
2339: Property 'category' does not exist on type 'CombinedVueInstance<Vue, object, object, object, Record<never, any>>'.
Anyway, luckily, I found this temporary solution.
