Hello,
I am learning the product attribute/variation system and came across an issue today. I created two "Test" attributes and enabled them on my Product Variation. I then created a test product and added variations based on those attributes.
My testing complete, I deleted the two "Test" attributes. Now, I am unable to access the edit screen of my product variation that had those attributes enabled. I have tried clearing cache, but that did not fix the issue.
The on-screen error is: "The website encountered an unexpected error. Please try again later."
The log error message is:

I'm sure i shouldn't have deleted the attribute the way that I did, but this seems like something that could be screwed up really easy, causing a website to partially crash like this. I do have a database backup, but I wanted to see if anyone could tell me how to fix the issue instead.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I'm somewhat shocked that this has not been dealt with. This is not some complicated task that a user would have to jump through loops to trigger. It completely breaks the "edit product variation" functionality until you manually delete the field from the variation.
