This a core problem #3406612: Exceptions in batch no longer are shown on the page: Javascript error so it should be fixed there.
But since we just released a beta it would be good to solve this. Otherwise anyone how uses our to update and has JS enable, 99% of users, will not see the error messages on the screen. this is will be very unhelpful if people start to beta test the module and run into problems.
We just haven't hit this in tests because we don't have many JS tests.
Put temporary fix into make sure errors on shown on the batch pages.
Show commandsStart within a Git clone of the project using the version control instructions.

phenaproximaThis is a reasonable workaround until the core bug is fixed. I think keeping the test coverage is also a wise decision, since 99.9% of people will use the batch system with JavaScript enabled.
