3057100 - Synchronization fails when mandatory attributes are undefined

1. After making a simple change like the name of one product and synchronizing that product alone, the sync fails.
   
   
2. The synchronization logs show that the job ended in with errors and unfinished items:

There were errors during the synchronization!

3. The last sync media, which contains the unfinished items, prints out the PK of the source/target version of the product(s), the PK of the itemsynctimestamp and the list of attributes that couldn't be synchronized. In reality, there can be as little as one attribute contributing to the entire sync failure, so the values printed can be misleading. For example:
