Testcafe aborts with ELIFECYCLE npm error and exit status 4

I knew this is most common issue with Testcafe but, I previously posted questions and solutions doesn't match/work to resolve my issue. Testcafe version 1.8.4, with allure reporting. I have configured few test suites running sequential in my project but, after first suite run testcafe terminate with the following error and abort the test run. npm ERR! code ELIFECYCLE npm ERR! errno 4 npm ERR! user-journey-tests@1.0.0 test:appjourneys:azure: TARGET_ENV=test DATA_CENTER=azwus2 testcafe 'chromium:headless:emulation' './journeys/app-journeys/*-spec.js' -r allure npm ERR! Exit status 4 npm ERR! npm ERR! Failed at the user-journey-tests@1.0.0 test:appjourneys:azure script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I merged my suite in to one single npm run - This helps to run the tests but still the error continues to show up at the end and build status is unstable. Any thoughts how to over come this? TIA.
