Blank stories result in "Timeout after 10000ms"

[moltar]

I have perfectly valid stories which begin with a blank screen. E.g. a story for a "hidden" state, for example. Which users can control with the Storybook controls. Loki seems to fail on these consistently with:

 FAIL  chrome.app/chrome.laptop/Foo
       Foo Story
       Timeout after 10000ms

I get the same error, unfortunately I also can't find how to fix it

Try to update loki till the latest version (0.34). I bumped into the same problem when updated SB till V7.
Previosly installed loki version was 0.31 now 0.34 and it works fine.

The same problem for me. Timeout error if I use "target": "chrome.app" but for "target": "chrome.docker" all works well.

` "loki": {

"configurations": {
  "chrome.desktop": {
    "target": "chrome.docker",
    "width": 1366,
    "height": 768,
    "deviceScaleFactor": 1,
    "mobile": false
  }
}

}`

It worked for me.

Use --chromeConcurrency 1

{
	"scripts": {
		"test:ui": "npx loki --chromeConcurrency 1 test",
         },
	"devDependencies": {	
		"loki": "^0.35.1",
		"storybook": "^8.4.7",
         },
	"loki": {
		"configurations": {
			"chrome.laptop": {
				"target": "chrome.app",
				"width": 1366,
				"height": 768,
				"deviceScaleFactor": 1,
				"mobile": false
			},
			"chrome.iphone7": {
				"target": "chrome.app",
				"preset": "iPhone 7"
			}
		}
	}
}
