I am trying to use the except\_file\_to\_exist via FileDataAsset and it’s failing as this expectation is not loaded into registry.

Failed at  
registry.py

\_registered\_expectation.get(expectation\_name)

I followed the blog [Great Expectations Blogs](https://greatexpectations.io/blog/welcome-to-great-expectations-filedataasset/)

Please provide any examples or pointers to solve this.
