I can't run the project through TestOps

I have a functional system automation project, it is run by chrome, but when I add it to TestOps, and I try to run through Grid it doesn’t open chrome, which makes the project never run successfully.

How do I get chrome to open when I run there?

Hi,
Could you explain your steps to run Grid ?

The first item to run is open Chrome, but this step already gives error.

Could you run your katalon project normally by GUI?
