Since (some arbitrary Lucee update) a few weeks ago, we've started seeing this error in one of our API handlers whose only job is to fetch some instances of data and display them. I know where in our code the stack is referencing (even though it's not listed) but I don't know why the Coldbox call is failing. Anybody seen this reference to

getObjectMetadata

returning null?

@sknowlton What version of ColdBox? Those line numbers don't line up with my local ColdBox repo

6.6.1

Interesting--

poolMetadata

is an instance of

java.util.concurrent.ConcurrentHashMap

Just Lucee

It seems that would have to be a race condition where the item was just removed from cache while another thread was in the process of trying to update that item's metadata. I'm not sure how the Lucee version would affect it however.

Might be a red herring, but the API endpoint hasn't changed in some time so it's odd that we're just now noticing it

I ran into this a year ago https://ortussolutions.atlassian.net/browse/CACHEBOX-66

Hm, possibly we updated to 6.6.1 during a period when there weren't many objects being returned by that endpoint. It's still pretty rare, three instances in three weeks
