I am having the same issue posted years ago in this thread: https://trailhead.salesforce.com/pt-BR/trailblazer-community/feed/0D54S00000BuH04SAF
This just started occurring last week, despite no changes to our gift entry template. The banner at the top of the gift entry form simply says "error", but when scrolling through the form I found that one custom checkbox will show "value not of required type:" and must be checked, then unchecked. The gift will not be added to the batch until ALL custom checkboxes have been interacted with, but at that point the gift can be successfully added and the batch will process correctly. This must be done for every single gift, and our form has 20 potential checkboxes, so the process is very time-consuming. Is there anything that can be done on our end to fix this? Or does this require a fix within NPSP that will get pushed out to users? Is anyone else experiencing this?
We started experiencing this problem yesterday. My understanding from this thread and others like it is that the checkboxes are passing a NULL value instead of false when there's no interaction with them. The fix seems to be to change the checkboxes in gift entry to true/false picklists to pass the proper value. I don't know why it was working and now it's not.
