What does this erorr message mean?

If I told you that "You require sunglasses or an umbrella but not both." you would have no idea if it is raining or not. When running my Blazor web application I get "EditForm requires a Model parameter, or an EditContext parameter, but not both". My code has:

<EditForm Model="@order" OnSubmit="OnSubmit">  

so as far as I know I am only using a Model parameter. I think use of the word 'Or' in error messages should be banned. My guess is that something has auto generated EditContext. Has anybody got any idea where to look?
