and thumbs up for your great work!

So I am trying to write some vitest unit test for an Edit component (and Create also) using the tutorial on your website.
So having a resource, and an edit component as follows:

<Edit> <SimpleForm> ..... </SimpleForm> </Edit>

So, when I try to write a test as follows:

describe(......
     it('.....', () => { 
       render(
         <AdminContext dataProvider={...someDataProvider...}>
           <MyEditComponent />
         </AdminContext>
       )
      })
)......

I get the following error:

 TypeError: Cannot read properties of undefined (reading 'toLowerCase')
