Did pulumi 3.0 introduce any changes to unit testing related to resource reads? I've updated the

pulumi.runtime.setMocks

. I have some tests that work fine before updating, but after updating fail with an error like

failed to read resource #user 'test-user' [aws:dynamodb/table:Table]: req.getCustom is not a function

yea the migration guide talks about the changes to

Mocks

: https://www.pulumi.com/docs/get-started/install/migrating-3.0/

Right, as mentioned I updated the mocks. I'm wondering if anything else might have changed.
