Unable to use Model.ToDebugString with EF Core 6 preview 4

Include your code

var result =dbContext.Model.ToDebugString(MetadataDebugStringOptions.LongDefault);

And I am not able to find “DesignTimeModel” mentioned in the error message anywhere.

Include stack traces

System.InvalidOperationException: The requested configuration is not stored in the read-optimized model, please use 'DbContext.DesignTimeModel'.
