Retrieving emotesets occasionally fails with error 500 (Internal server error)

Further information:
The successful responses all exist cached on one server. The unsuccessful responses are always MISS, MISS when it comes to being cached.

I have not yet seen any seattle server which has the emotes cached.

Success:

I’ll tweak the header settings and see if I can form a response type that doesn’t care about the server cache, but I would have expected this to always be reloading the emotes into the cache already on the servers based on the pragma - I’m not an expert, so we’ll see.
