Hi, @YaronMordAnaplan. Please follow the issue template, we need more information to reproduce the issue.

Either a complete code snippet and URL/HTML (if more than one file is needed, provide a GitHub repo and instructions to run the code), the specific versions used, or a more detailed description to help us understand the issue.

Note: If you cannot share your code and URL/HTML, any complete code snippet and URL/HTML that reproduces the issue is good enough.

Reply to this issue when all information is provided, thank you.

@YaronMordAnaplan can you try using a specific version of e.g node-chrome in your yml file. Considering that version 4.17.0 was only released 3 months ago, maybe try using an earlier version just to see if it resolves the issue. That would at least provide more insight as to whether the issue is related to versions
