I wonder if this is related to the fact that the jobqueue has been running for a while and maybe it had cached the message groups

Niklas Laxström, [21.05.19 19:28]
It might be useful to add an explicit local cache clear for message groups for that job

Abijeet Patro, [21.05.19 19:30]
autoimport doesn't currently trigger a recache?

Niklas Laxström, [21.05.19 19:31]
I believe it does, but the jobqueue process has a in process cache that doesn't get invalidated by that

Niklas Laxström, [21.05.19 19:33]
Alternative to dropping local caches would be to do it conditionally based on something like isValid() check on the global cache. But I don't know if such thing exists.

Niklas Laxström, [21.05.19 19:34]
if we are pedantic, I should say datacenter-local cache instead of global :)

After running createMessageIndex.php, translationaid API works fine.

Niklas Laxström, [21.05.19 19:38]
Yep, so we are quite sure that outdated messageindex was the reason
