It's hard to tell from this context. Can you post the code that generates the error? If this is occurring in a custom component you've written and don't want to post, I often find it helpful to try to recreate the error in a simple project that can be easily posted. – Dan Monego

I needed to wrap the tested component with the material UI theme provider.
