What is a relevant Language markup for LocalBusiness Schema

[SEO-learner-brandon]

I'm working on some LocalBusiness Schema for some websites our agency is working on and I'm getting multiple errors in Googles Structured Data Testing Tool.
First one: Property inLanguage is not recognized by Google for an object of type LocalBusiness. And neither is availableLanguage.

If anyone has any helpful information I would appreciate it.

What type of business is it?

Nothing specific or any other subcategories. Just Local Business.

knowsLanguage works for Organization but not LocalBusiness. You may be able to do it using additionalType: additionalType - schema.org Property
