Worker gets empty array from KV from time to time

I have a Worker which lists keys from KV, and then tries to get value for the first key, and from time to time it returns empty array: as a value. Any clue how to debug it?

If the return value contains list_complete: false and a cursor, there are more results available, even if the keys array is empty

I’ll put in a PR to clarify https://developers.cloudflare.com/workers/runtime-apis/kv/#more-detail
