WebDriver using edge browser not working in task scheduler

[MRAJ]

Hello,

I tried to schedule in task scheduler my webdriver UDF script using edge browser but it is not running and its failing but when i am running manually it is running fine without any issue. Please help if i am missing anywhere.

Post your script or a short "reproducer" script that we can run to observe the issue. Otherwise, we can only guess at what the problem might be.

P.S. Have you checked the log files? If so, what did you find there?

[MRAJ]

#include "wd_core.au3"
#include "wd_helper.au3"


$_WD_DEBUG = $_WD_DEBUG_None ; Could also use $_WD_DEBUG_Error
Local $sDesiredCapabilities, $sSession, $sElement

SetupEdge()
_WD_Startup()
Sleep(2000)
;_WD_ConsoleVisible()
$sSession = _WD_CreateSession($sDesiredCapabilities)
_WD_Navigate($sSession,"$URL")
Sleep(4000)
_WD_DeleteSession($sSession)
_WD_Shutdown()


Func SetupEdge()

_WD_Option('Driver', 'msedgedriver.exe')
_WD_Option('Port', 9515)
_WD_Option('DriverParams', '--verbose')

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"binary": "' & StringReplace (@ProgramFilesDir, "\", "/") & '/Microsoft/Edge/Application/msedge.exe", "excludeSwitches": [ "enable-automation"], "useAutomationExtension": false}}}}'

EndFunc

_WD_DeleteSession($sSession)
_WD_Shutdown()

It is just simple script to run the URL of the website. I am not able to find any logs , in Task scheduler i am just seeing task successfully started and finished. I am trying to get logs and let you know if i can reproduce.

[MRAJ]

Have you checked the log files? If so, what did you find there? - which log files you are talking, please let me know.

[Danp2]

Change this --

_WD_Option('DriverParams', '--verbose')

to something like this --

_WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\msedge.log"')

Adjust the path as needed to work in your environment

[Danp2]

You could also do something like this if you want to capture the UDF output --

; Comment out the following line in your script
;$_WD_DEBUG = $_WD_DEBUG_None ; Could also use $_WD_DEBUG_Error

$_WD_DEBUG = $_WD_DEBUG_Info ; Gives you the greatest level of details
_WD_Option('console', @ScriptDir & "\wdudf.log")

This will redirect the UDF output that normally goes to the Scite output panel to a file so that you can review it following the script execution.

Just tested a simple Edge script and it is working fine in task scheduler.

I compile it x86, and specify the location of the exe.  Run 1 time in 2 minutes.  Got it working..

[Danp2]

@Nine Likely the OP's issue is environmental. Could be as simple as a rights issue where the user account used to launch the task doesn't have access to the script's directory. Hard to say with the limited info provided.

[Nine]

If he can run it manually, he should have the rights to run under the same credentials with Task Scheduler, no ?  I suspect it is the way it was entered in Task Scheduler, but like you said we do not have much info...

[MRAJ]

Attached are the logs. I am seeing in logs msedge is crashing due to RESPONSE InitSession ERROR unknown error: MSEdge failed to start: exited normally.
  (unknown error: DevToolsActivePort file doesn't exist), while running this error is not visible.

Are you using a sandbox or something similar :

Quote

options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model

 

[MRAJ]

Do you mean test box. Yes it is test server but i am not able to run on my local machine and even Prod..

[Danp2]

@MRAJ This issue has been discussed in great detail on the net. Just Google on the phrase "webdriver DevToolsActivePort file doesn't exist" and you'll find lots of discussion and potential solutions.

Can you tell us more about the task you created? Does the task execute under the logged in user's credentials?

[MRAJ]

Yes it is run under logged in users credentials

[MRAJ]

I am running many websites using IE same way and it is running fine.

[Danp2]

@MRAJ You continue to provide only minimal details in your responses. You can't expect us to work harder than you to try to solve your problem. Therefore, I am unwilling to help you further until you can show that you've researched the issue and tried some of the recommended solutions.

Hello Dan,

I tried solution like giving admin privilege to my scripts, path, even i changed the msedge to script directory, and schedule in task schedule like account to run which i logged in and script path to run. I search in net but not getting proper answer what i am doing through scheduling the script. upgrading and downloading the newer version of browser and webdriver. Still i am researching on this. As it is running manually without any issue but if i schedule it is giving me issue.

[MRAJ]

I just created a task like use the account which i logged in, Run only when user is logged in, Run with highest privileges, configure for OS, run every 5 mins,

Actions: path of the exe file.  and below is the page it will load and it will not go further, i tried to run using batch script and gave the path of the script and browser if may be exe file it is not accepting. I am not sure may be some compatible issue with Task scheduler or is there any bug with edge browser. Still i am trying best but not success still. and in net i found the below but not sure where to add. I tried to run using user account not admin but still same issue.

options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model

These would become part of your DesiredCapabilities string. Previous example posted here.

Does the behavior change if you don't check the "Run with highest privileges" box?

 

[MRAJ]

Hello Dan,

Yes its working after changing unchecking the "Run with highest privileges" box. Cool Dan. You are best.
