Error when trying to set mockAddonConfigs in main.js

[davidpmccormick]

Adding the mockAddonConfigs block results in undefined is not iterable (cannot read property Symbol(Symbol.iterator))

Storybook 8.3.5

Facing the same issue. Stack is based on nx monorepo + angular + storybook. Storybook version 8.3.2 (Tried to downgrade to version 8.2 same issue happened)

I have Storybook 8.4.1 and I am facing the same issues

I had the same problem. I fixed it by adding an empty array in mockAddonConfigs , i.e.
mockAddonConfigs: { globalMockData: [] }
