Codeceptjs Headless tests with https do not work - selenium

Question

When i run tests with https headless, the error below shows up
bash
Error: move target out of bounds: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.
Running without --headless option, it works but slower.
Running as http with --headless works too

Answer 1

Try using an x instead of a comma (,) when specifying the window size.
Example:
--window-size=1920x1080

Answer 2

Maybe this is related to this:

You could create Chrome profile where you will turn off this option and load it by providing run parameter (https://chromium.googlesource.com/chromium/src/+/HEAD/docs/user_data_dir.md):
"chromeOptions": {
"args":[
"--window-size=1200,1200",
"--headless",
"--user-data-dir=<YOURDIR>]
}
Another solution you could check if UserAgent string for headless is different than normal browser, and if answer is yes override it with (Chrome 69 UA):
"chromeOptions": {
"args":[
"--window-size=1200,1200",
"--headless",
"--user-agent="Mozilla/5.0 AppleWebKit (KHTML, like Gecko) Chrome/69.0 Safari"]
}
And the last one is to turn off security policy by providing parameters:
--disable-web-security
--allow-running-insecure-content
"chromeOptions": {
"args":[
"--window-size=1200,1200",
"--headless",
"--disable-web-security",
"--allow-running-insecure-content"]
}
You can try one of the possible solutions or combine them.
