Cannot submit Purchase Invoice; set_missing_ref_details() unexpected... ref_exchange_rate

I have Debian 12; ERPNext: v15.19.2 (version-15); Frappe Framework: v15.20.0 (version-15) which I just updated earlier today (frappe/ERPNext and O/S all to latest).

All worked perfectly until after the update.
The 1 part that has suddenly started giving an error, is submitting a purchase invoice, which throws out this

### App Versions

	"erpnext": "15.19.2",
