Testcafe screenshot is not working for firefox on Cent os

[sumant28]

Scenario :
1] Using frontend-maven-plugin to download node and testcafe in project directory.
2] Running testcafe based tests from Java using xvfb-run command along with node and testcafe using code like :
Runtime.getRuntime().exec()
3] Using .testcaferc.json to add configuration where the screenshot is enabled.

The actual command that is running :
xvfb-run --server-num=43717 --server-args=-screen 0 1024x768x24 {project_root_path}/node/node {project_root_path}/node_modules/testcafe/lib/cli/cli.js 'path:/mnt/jenkins/firefox/firefox-68.1.0esr/firefox/firefox --start-fullscreen' {project_root_path}/src/test/resources/testcafe-test-files/transform-add-and-subtract-time.js

The error while taking the screenshot is :

Warnings (2): -- Was unable to take a screenshot due to an error.

  `Error: Command failed:
  {project_root_path}/node_modules/testcafe-browser-tools/bin/linux/glibc-64/screenshot
  200002
  {project_root_path}/target/screenshots/Add Time.png`

Software versions I am using :
Testcafe version : 1.1.0
FirefoxBinary version: Mozilla Firefox 68.1.0esr
CentOS version : Linux release 7.4.1708 (Core)

Can you please help me in resolving this issue ?

FYI,
I am seeing this issue only on centos servers and firefox full-screen mode. And I am running my test using Jenkins.
Testcafe is able to take a screenshot on my local Mac machine for both firefox and chrome

Hello @sumant28 ,

The log you provided is a TestCafe error log. Please execute the ldd /node_modules/testcafe-browser-tools/bin/linux/glibc-64/screenshot command and send us its output. Also, you can try to use a headless mode to avoid the issue.
