Hi Justin, we re-added PyOP2 type-checking, which validates that you're iterating over compatible sets. Plausibly you weren't doing that. You can set: parameters["pyop2_options"]["type_check"] = False in the short term. Can you please report this as a github issue so it doesn't get lost over Christmas!

Hi all,
Just made an update to firedrake, and my code breaks down with this PyOP2 error:
Traceback (most recent call last):

It worked previously, I am guessing the latest change to PyOP2 changed a few things here and there. Attached is the code and the PyOP2 kernel.
Thanks, Justin
