React-Admin is a great tool for creating admin interfaces, but one issue you may run into is fetching the X-Total-count Header when using CORS. This can be fixed by setting the “Access-Control-Expose-Headers” header in your server’s response.
Example Asp.net, program.cs
app.UseCors(builder => builder .AllowAnyOrigin() .AllowAnyMethod() .AllowAnyHeader() .WithExposedHeaders("X-Total-Count") );
