Steps to reproduce:
Given an authorized user (i.e. diku_admin in folio-edelweiss.dev.folio.org)
Goes to Settings>Circulation>Fee Fine>Overdue fine policies
Fills in every field
Clicks save and close
Policy saved and screen closes
Blank red "toast" appears and the policy is not saved.
NOTE The error does not occur on https://folio-snapshot.aws.indexdata.com/ and https://folio-testing.aws.indexdata.com/. It does occur on https://bugfest.folio.ebsco.com/ and https://snapshot-core-continuous.dev.folio.org/. Unable to test
CIRC-524 until this is fixed. Also, this error did not occur on BUGFEST until recently.
