I just wanted to add the examples here, but ended up having to replace the NULLs as it wouldn't pass the checks with them in place.

I'm pretty confident I didn't break anything, but thought it safer to ask for review on this occasion.

@mdpointer - Yes, null values aren't valid in the register JSON, so replacing them was the right thing to do.

One thing I'm curious about, though: how did the JSON end up with null values in the first place? The generator at https://org-id.github.io/register/datatig/type/lists/newweb/ creates empty strings ("") and empty arrays ([]) rather than null, and the other lists we've used as examples also use "" for blank values if they've been used as a template.

Just wondering what workflow generated the nulls.

@leilafarsani
I don't know - the list was created 9 years ago and I was just inserting the examples (for UPDATE: KE-NCB - Add example identifiers #710)

@mdpointer - That makes sense. The schema must have changed since then. The current version is here:

https://org-idguide-handbook.readthedocs.io/en/latest/schema.html

You can see the valid data types there.
