I pinged @bvibber on Slack as they have done some work on JsonConfig recently for T388434: JsonConfig remote-data-with-Lua-transform API query. I'm not sure that these errors were a direct result at all, the stacktrace for the [{reqId}] {exception_url} TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given for looks like bad/unexpected data going boom in code paths unchanged for years. Maybe there is new usage of things that is exposing weak data validation somewhere along the line?

I'm suspicious that this may have been caused by recent changes to JCCache causing null values to end up somewhere, but I haven't narrowed down exactly how if so:

This one is resolved with the revert of the JCCache changes. That may have squashed all of them, but lets leave this open for a bit to be more certain.
