Cannot edit a campout - Error message when trying to save edits

I am getting an error message while saving after I added scouts to a campout.
Can I please get help with this?

I get this error trying to save service activities as well.

Having same issues on the last two days was able to submit but not correct entries. Any updates or feedback on this?

Yesterday I couldn’t save my edits (That error kept popping up) but when I opened the campout today it had all my edits saved.
I hope this issue was resolved for everyone!

These are known issues that are being worked on

Same happened for me. I got an error on saving, but when I refreshed the window, all was OK
