If chromatic.config.json has storybookBuildDir configured, a build is not triggered

[rhuanbarreto]

Describe the bug

I separately build the storybook for caching purposes in CI so we speed up the process in our monorepo. And for this I use the storybookBuildDir option in the chromatic.config.json file.

But when I push the play button in the storybook interface, the chromatic command fails:

Invalid Storybook build at storybook-static: ENOENT: no such file or directory, scandir 'storybook-static'

This is because in development, the developers don't build the storybook locally, which is fine.

I understand that the addon just delegates the build responsibility to the chromatic command. But could either the addon or the chromatic command trigger a build if there's nothing on the storybookBuildDir?

To reproduce

1. Setup chromatic.config.json with storybookBuildDir
2. Remove the storybookBuildDir folder if there's any
3. Start the storybook: storybook dev -p 6006
4. Push the play button to trigger the visual tests addon
5. The underlying chromatic command should fail
