Errors for missing pieces should suggest rerunning the cache.

What happens if someone who ran LOLAweb with an old version tries to load that cache with an updated LOLAweb?

Well, the old versionw ill lack a few components from the new. If you run a cache in an older version of LOLA web, then try to load it in a new version, missing components give you an error like this:

Error: An error has occurred. Check your logs or contact the app author for clarification.

I think this should be a more informative message, if the requested object is simply not found (it could suggest re-running the cache for example).

If there truly was an error then it's fine to say that, otherwise, I think that's not the right message to send.

@vpnagraj this comes up again with the new genomic distributions plot, which doesn't show up for sample data.

i believe #66 and #101 now encompass this issue

closing this for now ... we can always reopen if needed
