Getting a list with CSOM
In my PowerShell script I’m doing the following:
$list = $web.Lists[“Mylist”]
This generates the following Unexpected error in my SharePoint logs:
8ca3ea94-3288-49cd-99fd-1b6eab6cb52d Stack trace: at Microsoft.SharePoint.SPListCollection.GetListByName(String strListName, Boolean bThrowException) at CallSite.Target(Closure , CallSite , Object , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecute2[T0,T1,TRet](CallSite site, T0 arg0, T1 arg1) at System.Management.Automation.Interpreter.DynamicInstruction`3.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.Interpreter.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.LightLambda.RunVoid1[T0](T0 arg0)
Am I doing something wrong. Not really as I’m getting my list object from SharePoint and all seems to be working.
I don’t like unexpected error as they tend to point towards something that isn’t handled properly.
How about using the GetList method?
I changed my code to:
$ulsList = $web.GetList($web.Url + “/lists/” + $ULSListName)
One Unexpected is now replaced with another one:
c50dac63-ae98-4054-9cb9-615373cfd553 Stack trace: at Microsoft.SharePoint.SPWeb.GetList(String strUrl) at CallSite.Target(Closure , CallSite , Object , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecute2[T0,T1,TRet](CallSite site, T0 arg0, T1 arg1) at System.Management.Automation.Interpreter.DynamicInstruction`3.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.Interpreter.Run(InterpretedFrame frame) at System.Management.Automation.Interpreter.LightLambda.RunVoid1[T0](T0 arg0) at System.Management.Automation.DlrScriptCom…
hmm, So what could be the issue?
Get a list using TryGetList
Then I tried another option
$ulsList = $web.Lists.TryGetList($ULSListName)
No more errors.
How many options can there be to get a list???
