uploadRobotFile returns Action Error : java.lang.NullPointerException

[j0hnsa]

Hello, while trying to use the uploadRobotFile action a java.lang.NullPointerException occurs.

the action is configured like this:

Can you please advise?

Can you confirm that the robot extention runs on a windows system ? You configured a Windows path and logs looks like docker based so I guess running under Linux. If using a standard docker image path should be more like /home/seluser/Downloads/test.json That way the file will be created on the robot side directly inside Download folder. Ready to be uploaded from the browser to your application.

It does run on windows system, is this action limited to linux hosts?

[vertigo17]

There are no reason that this shouls not work on windows. I will have a look why npe was raized

I've tested with linux and the error seems to be present too, maybe I'm missing something

Thanks for the log. I will try to reproduce that.

A couple of question that may help to identify the issue: Did you secure that folder C:\CerberusData\ or whatever folder you specified on your test under a linux docker image existed ? Can you test putting /home/seluser./downloads/test.json after making sure that folder /home/seluser/Downloads/ exist ? Also secure that parameter -a (--authorisedFolderScope) has been feed with /home/seluser/Downloads/ or docker compose include it this way:

  selenium-node-chrome:
    image: cerberus-node-chrome
    environment:
      HUB_HOST: selenium-hub
      SE_OPTS: -servlets org.cerberus.robot.extension.sikuli.ExecuteSikuliAction -servlets org.cerberus.robot.extension.filemanagement.ExecuteFilemanagementAction -servlets org.cerberus.robot.extension.management.ExecuteManagementAction
      JAVA_OPTS: -DauthorisedFolderScope=/home/seluser/Downloads
    depends_on:
      - selenium-hub
    expose:
      - "5900"
    ports:
      - "XXXXXX:5900"
    volumes:
      - /etc/localtime:/etc/localtime:ro
    restart: always
    shm_size: 512mb
    deploy:
      resources:
        limits:
          cpus: '0.8'
          memory: 1548M

From your logs, I see that -a (--authorisedFolderScope) has been feed with null. For sure that will have a strange behaviour. Let me know when you can test with that parameter defined.

I'm not being able to launch a node with the argument -a, an exception is raised, can you please advise on how to use it?

Below is one example of the command I tried to use with the -a:

java -cp "selenium-server-standalone-3.141.59.jar;cerberus-robot-extension-1.8-SNAPSHOT-full.jar" org.openqa.grid.selenium.GridLauncherV3 -role node -hub http://127.0.0.1:4444/grid/register -port 4445 -a "C:\selenium" -servlets org.sikuliserver.ExecuteSikuliAction -servlets org.cerberus.robot.extension.sikuli.ExecuteSikuliAction -servlets org.cerberus.robot.extension.filemanagement.ExecuteFilemanagementAction -servlets org.cerberus.robot.extension.management.ExecuteManagementAction Exception in thread "main" com.beust.jcommander.ParameterException: Was passed main parameter '-a' but no main parameter was defined in your arg class at com.beust.jcommander.JCommander.initMainParameterValue(JCommander.java:936) at com.beust.jcommander.JCommander.parseValues(JCommander.java:752) at com.beust.jcommander.JCommander.parse(JCommander.java:340) at com.beust.jcommander.JCommander.parse(JCommander.java:319) at org.openqa.grid.selenium.GridLauncherV3.parse(GridLauncherV3.java:218) at org.openqa.grid.selenium.GridLauncherV3.lambda$buildLaunchers$7(GridLauncherV3.java:271) at org.openqa.grid.selenium.GridLauncherV3.lambda$launch$0(GridLauncherV3.java:86) at java.base/java.util.Optional.map(Optional.java:265) at org.openqa.grid.selenium.GridLauncherV3.launch(GridLauncherV3.java:86) at org.openqa.grid.selenium.GridLauncherV3.main(GridLauncherV3.java:70)
