TypeError: storyStore.getError is not a function (After installing @storybook/addon-storyshots)

[rimatla]

Describe the bug
After installing @storybook/addon-storyshots: 5.3.10 or 6.0.0-alpha.4 storybook breakes in the browser and it errors: TypeError: storyStore.getError is not a function

We're in the process of upgrading to Storybook 5.3.10.
Without the Storyshots addon, everything builds correctly in the browser. 🎉

After following these instructions. Which docs states to require minimal set up if stories are wired to the main.js new syntax.

• Installing a lower release of @storybook/addon-storyshots after running yarn test. Tests fail and I get the following error: Test suite failed to run: Cannot find module 'core-js/modules/es.array.for-each' from 'index.js'. But it does not prevent storybook to render without problems in the browser

• Installing every addon (actions, storyshots, a11y) + storybook/react to be on the same version "5.3.10" or 5.3.9 after running yarn test. Tests passes and snapshots are created correctly. But storybook breaks and fails to render.

So the caveat here is that my stories seem to be wired correctly per the migration guide.
But the existence or absence of '@storybook/addon-storyshots' either gives me passing tests or stories rendering as CSF
but not both. 😿

To Reproduce
Steps to reproduce the behavior:

1. Install react storybook and storyshots addon "5.3.10"

Expected behavior
Storybook should render correctly in the browser and snapshot add-on should read from Storyshots.test.js accordingly.
