Comment (by MikeNGarrett):

 I've opened and closed a business, changed cities,  bought a house,
 started a family, and gone through a pandemic since I opened this ticket.

 ...but for some reason I still remember the details of this ticket.

 Yes, the issue is that null values in an array are cast to empty strings
 when being stored in the database. In cache, they are correctly stored as
 null.
