We're intermittently getting this error (so far twice in 2 weeks) when trying to use the lookup command on a kvstore.
The full error message is " External command based lookup <kv_store> is not available because KV Store status is currently unknown".
We only found the error through the logs a few hours after the failure because the scheduled search with the lookup command didn't run successfully. When ran manually or on its next schedule, the search was running fine. KV store is also working as intended upon checking.
I couldn't find information online on what the "unknown" status means regarding kv stores.
Has anyone else seen this error?
This probably means your KVStore is down. It is probably related to the WiredTiger upgrade. Use the CLI to debug and fix:

Did you ever figure this out? I'm seeing the same problem.
