The undo API has changed with ZODB 3.10. As noted in the changelog:

"The API for undoing multiple transactions has changed. To undo
multiple transactions in a single transaction, pass a list of
transaction identifiers to a database's undoMultiple method. Calling a
database's undo method multiple times in the same transaction now
raises an exception."

Your code calls undo multiple times, and needs to be changed accordingly.
