Hi! The problem here is that you're running the built-in ner.manual command, not your custom recipe, which is called custom_recipe. So to run that recipe from the file, you want to start with prodigy custom_recipe.
Your custom recipe should also include the required arguments that you want to pass in – at the moment, it's only taking a name of a dataset and a positional argument lang, and it's not actually returning a "stream" of examples to annotate. Instead, you probably want to model your recipe after the existing ner.manual and include all the required CLI options, as well as tokenization within the recipe, loading the stream etc:
