Rather than test on the function level - we don't have any other tests like this. Can you do a high level set of inserts/queries which reproduce the issue please? Add to https://github.com/ClickHouse/clickhouse-go/blob/main/tests/json_test.go

I don't know all the implementations very well, it's a bit of a hassle, I'll give it a try

Is it okay to submit a commit like this?

[gingerwizard]

OK post some JSON which recreates your issue @ACV-er - I'll write a test.

What are these errors? It doesn't look like a problem with the code。 @gingerwizard

@ACV-er our cloud CI tests wont pass for external contributors as you don't have access to cluster secrets. Needs to be fixed. I'll test locally today and merge. thanks again. Will make 2.4.2 - likely end of week.
