When I build with StencilJs 2.5.2 and Typescript 4.5.2, I get the following Typescript error:
```
[ ERROR ] TypeScript: ./node_modules/@storybook/client-api/dist/ts3.9/index.d.ts:4:1
Module './types' has already exported a member named 'RenderContext'. Consider explicitly re-exporting to
resolve the ambiguity.
L3: export * from './queryparams';
L4: export * from '@storybook/store';
L5: export { addArgsEnhancer, addArgTypesEnhancer, addDecorator, addLoader, addParameters, setGlobalRender, ClientApi, };
[ ERROR ] TypeScript: ./node_modules/@storybook/client-api/dist/ts3.9/index.d.ts:4:1
Module './types' has already exported a member named 'StorySpecifier'. Consider explicitly re-exporting to
resolve the ambiguity.
L3: export * from './queryparams';
L4: export * from '@storybook/store';
L5: export { addArgsEnhancer, addArgTypesEnhancer, addDecorator, addLoader, addParameters, setGlobalRender, ClientApi, };
```
So `types.d.ts` has
```
export declare type StorySpecifier = StoryId | {
name: StoryName;
kind: StoryKind;
} | '*';
export declare type RenderContext = RenderContextWithoutStoryContext & {
storyContext: StoryContext;
};
```
while `index.d.ts` is
```
import { ClientApi, addDecorator, addParameters, addLoader, addArgsEnhancer, addArgTypesEnhancer, setGlobalRender } from './ClientApi';
export * from './types';
export * from './queryparams';
export * from '@storybook/store';
export { addArgsEnhancer, addArgTypesEnhancer, addDecorator, addLoader, addParameters, setGlobalRender, ClientApi, };
```
If you look at `index.d.ts`, there is another import from `ClientApi`, whose members are explicitly exported by name, not by *. I think that's the way to go.
Sidenote: It seems that Storybook only implemented Typescript 3.9, perhaps that's why the error didn't occur in your build yet. Also the error appeared with Storybook 6.4.1, it wasn't in 6.3.12.
