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.

• Please share node version. Are you importing 'node:stream' or is it just jest doing something internally? – sziraqui Commented Jan 29 at 14:41
• @sziraqui - using node version - 14.21.1. not importing anything in the code, something jest calling internally. – nari447 Commented Jan 29 at 15:01
