Hello People, I am trying to follow documentation to add custom entity field in customer registration form. After adding entry point files and views, when I try to run my extension locally; I get this error. What's the reason for this? Any help is appreciated. Thanks!

It makes me think your .tpl files aren't loading or are missing - do you have your template file referenced in your views, the manifest.json, and in the file structure?

I do. I just double checked and I am referencing the .tpl file correctly in my LoginRegisterView and in manifest.json as well.
