Additional info

Loki works with running storybook (not static). Problem only with static-storybook.

Loki 0.31.1 works with Storybook 7.6.17 Loki 0.31.1 does not works with Storybook 8.5.7 Loki 0.35.1 does not works with Storybook 7.6.17 Loki 0.35.1 does not works with Storybook 8.5.7

Tested with Node v22.14.0.

(in different versions combination error changes)

Looks like https://github.com/oblador/loki/issues/503 does not fixed for storybook-static.

@PFight if you serve your static-storybook with http-server for example like this: pnpm http-server ./storybook-static --port 6006 is it being served? and then when you try to run for example pnpm loki test does it work for you?

npx http-server ./storybook-static --port 6006                               
Starting up http-server, serving ./storybook-static

I had checked that it was indeed there and accessible. Then ran loki:

npm run loki

Yes, it work. I wrote this in the topic:

Update: workaround with older package versions does not work with Chrome 109.0.5414.120. With Chrome 134.0.6998.89 works.

In loki.config.js if I use chrome.docker and run yarn loki --requireReference --reactUri file:./storybook-static It will work fine but if I use chrome.app it logs this error
