Getting AJAX HTTP error occurred

Problem/Motivation

I'm trying to use Entity Delete current version (also tried dev-2.0.x) and when trying to delete all entities for the entity of type "Transaction" I get the following:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /batch?id=169&op=do_nojs&op=do
StatusText: parsererror
ResponseText: Error: Call to a member function getTargetEntityTypeId() on null in Drupal\transaction\Entity\Transaction->urlRouteParameters() (line 585 of /var/www/html/web/modules/contrib/transaction/src/Entity/Transaction.php).

Steps to reproduce

Install Entity Delete on a site that has the Transaction module installed
Use Entity Delete to delete Transaction entities
