Exception when cd-ing

[bwets]

I get this when I cd to a folder:

System.Management.Automation.RuntimeException: You cannot call a method on a null-valued expression. at System.Management.Automation.ExceptionHandlingOps.CheckActionPreference(FunctionContext funcContext, Exception exception) at System.Management.Automation.Interpreter.ActionCallInstruction2.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.ScriptBlock.InvokeWithPipeImpl(ScriptBlockClauseToInvoke clauseToInvoke, Boolean createLocalScope, Dictionary2 functionsToDefine, List1 variablesToDefine, ErrorHandlingBehavior errorHandlingBehavior, Object dollarUnder, Object input, Object scriptThis, Pipe outputPipe, InvocationInfo invocationInfo, Object[] args) at System.Management.Automation.ScriptBlock.<>c__DisplayClass57_0.<InvokeWithPipe>b__0() at System.Management.Automation.Runspaces.RunspaceBase.RunActionIfNoRunningPipelinesWithThreadCheck(Action action) at System.Management.Automation.ScriptBlock.InvokeWithPipe(Boolean useLocalScope, ErrorHandlingBehavior errorHandlingBehavior, Object dollarUnder, Object input, Object scriptThis, Pipe outputPipe, InvocationInfo invocationInfo, Boolean propagateAllExceptionsToTop, List1 variablesToDefine, Dictionary`2 functionsToDefine, Object[] args) at System.Management.Automation.ScriptBlock.InvokeUsingCmdlet(Cmdlet contextCmdlet, Boolean useLocalScope, ErrorHandlingBehavior errorHandlingBehavior, Object dollarUnder, Object input, Object scriptThis, Object[] args) at Microsoft.PowerShell.Commands.ForEachObjectCommand.ProcessRecord() at System.Management.Automation.CommandProcessor.ProcessRecord()

It comes from z as it does not happens when the module is not loaded. It also started recently, even after updating to latest 1.1.19.

I should note that it happens on Windows 10 Fall Creators Update build 16299.15

Any idea?

[badmotorfinger]

Is this any folder? Can you please give me the example of folder name.

[bwets]

any folder like c:\Windows. Rooted or not is the same Edit: also when cd ..

[badmotorfinger]

Can you please send me your z.psm1 file? I'd like to try it.

[bwets]

here it is, renamed to .txt z.txt

BTW, I dont seem to have this issue in elevated ps

[badmotorfinger]

Thank you so much for helping me out here. Can you please try the attached file? z.txt

Also can you please provide me with a list of modules which you currently have loaded? You can get this by running Get-Module

[bwets]

nope, still not ok

ModuleType Version Name ExportedCommands

Script 1.1.9 z {cdX, popdX, pushdX, z}

[badmotorfinger]

Also you said this happened recently, was this previously working?

[bwets]

yes it was working like a week ago

[badmotorfinger]

One last request, would it at all be possible to send me your .cdHistory file? If that's too sensitive then I'll need to try another approach.

I've also attached a ps1 file which you can load up in PowerShell ISE and run. It will try to CD into C:\Windows. Hopefully it will tell you the line it's failing at.

z.ps1.txt

[bwets]

ok, I see that the exception happens when saving the history My jump-location is huge, because it has detected all subfolders from a git root It is like 600k and is being written constantly. I guess you could ignore .git folders when inspecting a folder structure...

[bwets]

ok, forget lat comment, thats an other thing... It is not happening anymore (the exception) and that is since I closed an other instance of ps. Maybe some kind of race situation for saving the history? BTW, my .cdHistory only contained one folder, C:\Work\Sandbox

Anyway, I dont know why it is working again...

[badmotorfinger]

That is bizarre. I usually run multiple PowerShell sessions.

Thank you for taking the time to help me on this.

[bwets]

Well, thank you for trying to fix the problem. I will keep you informed if there is anything new on this.

[nzbart]

This problem is now happening to me. Should I open a new Github issue?

I also don't get this issue in an elevated PS instance.

This is the output of Get-Module:

[badmotorfinger]

Would it be too much trouble to send me your history file via e-mail? I suspect it's something to do in their.

Also could you tell me which OS and version you are using as well as the language it's running under?

Thanks

[nzbart]

No problem; would I send it to p***e@gmail.com?

I'm running Windows 10.0.16299.309. More info:

[badmotorfinger]

If you could send it to me that would be great.

[nzbart]

Did you receive the file that I sent?

[badmotorfinger]

File received thanks. Looks like there's nothing out of the ordinary going on.

I really don't know what the issue is. Your file is not corrupted in anyway.

I suggest you delete your .cdHistory file and launch a powershell session again. If that doesn't work, you might need to assist me in debugging :)

[nzbart]

Hi @vincpa ,

I deleted the .cdHistory file and opened a new PowerShell window. It appears to be working now. I'll let you know if it stops working again.

Thanks!

[badmotorfinger]

I wonder if this has something to do with file permissions.

Thanks for your time guys.
