500 Error when I click on Platform link from TIPP page

[jhsolomon]

I tried to update the Platform on this title: https://gokb.openlibraryfoundation.org/gokb/resource/show/org.gokb.cred.TitleInstancePackagePlatform%3A30666070

But got an error. Can you take a look?

So - the intention, I believe, was that tipps must always be immutable - IE you can't update a platform on a tipp, you have to create a new tipp and retire the old one. We shouldn't ever have a situation where a tipp has no platform, as here - and the link is not an edit link, but a "follow" link. The error page is popping up because there is no platform. So - this isn't so much about editing platforms, as how the heck did we end up with a tipp that has no platform - that shouldn't happen. We need to dig in and see how many places this happens and see if we can figure out any pattern to it. Do you have any ideas as to why this particular one might not have a platform to begin with? @sosguthorpe do you have any thoughts?

That makes sense!

I was adding a new title to the package based on the publisher's page, and I clicked add before I manually add the platform with it. I think this is a very small usecase, but it seems to me that no one should be allowed to manually add a title to a package without also indicating the platform.
