@thandaanda It works! Thank you so much.

For anyone else lurking - pop that in your compilerOptions and that should work a treat. As it did for me - thanks @thandaanda !

i have added "emitDecoratorMetadata": true in .storybook/tsconfig.json

{
  "extends": "../tsconfig.app.json",
  "compilerOptions": {
    "types": [
      "node"
    ],
    "emitDecoratorMetadata": true
  },
  "exclude": [
    "../src/test.ts",
    "../src/**/*.spec.ts",
    "../projects/**/*.spec.ts"
  ],
  "include": [
    "../src/**/*",
    "../projects/**/*"
  ]
}
