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")

);
