Why is the supplier item number causing receipt error in redwood Orders to receive

We have noticed recently that we are getting an error message on the receiving page when we click create receipt.
the submit drawer opens and when we click Submit we get the following error.

our investigation brought us to the Supplier Item that was entered had a space at the end of it.
We performed a CO and updated the Supplier Item #, and it worked fine.

We never had this issue before. Is this new with Redwood or is it something that came with an update we missed?
