we are upgrading from Jest 23 to 26
seeing below error on running jest after the upgrade,
even tried install stream package and no luck with that. any help understanding why jest-runtime is not finding the package inside node modules

Edit 1:
got past above error with - Jest Unit tests are failing
which helped pass some tests, but seeing another error with rest of the tests as below
TypeError: Invalid attempt to spread non-iterable instance. In order to be iterable, non-array objects must have a Symbol.iterator method.
