Expense Claim can't be cancelled

https://github.com/frappe/erpnext/issues/13694

I think it is clear from the trace, expense claim is validated in a way that it can’t be cancelled if it has a submitted payment entry so if you want to cancel the expense claim you firstly should cancel its linked payment entry

hope this helps

Of course… if “Is Paid” wasn’t checked a message informs that there’s a linked Payment.

But if “Is Paid” was checked…
