Test fails with "Failed to locate opened application window with appId"

Hi all, I started having this problem when the driver fails to locate the app around a month ago. I am getting it approximately 3/4 times I am trying to run tests. Right now it makes it impossible to have a stable automation running.

Here is the full log: (I replaced app path with xxx…)

The test obviously fails but the app is actually launched. So location is not an issue. Is there something I am doing wrong? It used to work fine…?

I am using Appium from node version 1.7.2 WindowsDriver (v1.0.0)

Many thanks, Ewa

Try to include below capability which solved my issue of Failed to locate opened application window with appId"xxx" and process “xxx”

My exe file present in C:\Program Files\MT

appCapabilities.SetCapability(“appWorkingDir”, “C:\Program Files\MT”);

@balaji-githubstore How did that work, I thought that SetCapability was depreciated.
