An unknown server-side error occurred while processing the command. Original error: [object Object] while launching app which has splash screen on windows 10

[KrishnaKokila]

When i try to launch a wpf application which has a splash screen at the start gives the following error.

Test method winAppTest.UnitTest1.TestMethod1 threw exception:
System.InvalidOperationException: An unknown server-side error occurred while processing the command. Original error: [object Object]

It does open the app but looks like its searching for the process name of the splash screen which shows no name in task manager. it does show login window after launching.

Any help?

Hi @KrishnaKokila,

Would you check out issue #213 and try the resolution? This resolution has addressed many splash screen behavior experienced by others.

Thanks @timotiusmargo , but unfortunately that solution didnt help since i get an error while performing launch of the application.

attached exception for reference

Hi @KrishnaKokila,

Can you provide the WinAppDriver.exe console output of your session creation like below?

==========================================
POST /session HTTP/1.1
Accept: application/json, image/png

This should show the reason why the session creation failed.

Hi @KrishnaKokila

Can you try this with a more current build of Appium WinAppDriver? This seems to be a fairly old version of WinAppDriver that is being invoked.

Thanks
