"Error: Component must be wrapped with <Container.Provider>" in Next.js

[remjx]

I'm getting this error when trying to implement WalletKit in Next.js:

error - Error: Component must be wrapped with <Container.Provider>

But I do have the hook wrapped in the WalletKit provider as in the example. What could this this error be indicating?
