Error in Bootstrap.Octopus.AzureContext.ps1: $MyInvocation.MyCommand.Path is null

Hi there

I’m trying to execute an Azure PowerShell deployment step, which is consistently failing with the error

Split-Path : Cannot bind argument to parameter 'Path' because it is null.
At C:\ProgramData\Octopus\Work\20161013155154-9\Bootstrap.Octopus.AzureContext.ps1:1572 char:25

mmand
The remote script failed with exit code 1

The script that I’ve added to the deployment step is really simple:

Invoke-Psake `
    -framework 4.6 `
    -buildFile "Scripts\deploy.ps1" `
    -properties @{ "ClusterName"=$EnvironmentShortName }

Invoke-Psake is defined in a script module, which is a copy-paste job on this file. I get the exact same result (no output) if I add a Write-Host statement at the start of my script.

I’ve attached the log file to this post. I’m using v3.4.10.

In fact, if I comment out the Invoke-psake command and just leave the script as a simple Write-Host statement, I see exactly the same behaviour. Is this step broken somehow, or missing a piece of configuration perhaps?

Tried upgrading to 3.4.12 - same result.

Some further investigation indicates that it’s the Psake Script Module that’s somehow interfering with the process - not sure why right now.

Hi Alastair,

Thanks for reaching out! Does seem like there’s something wrong with Psake or the day its being loaded. What I would try is, instead of loading it from the Octopus Script Module, simply installing it on the server on one of the paths of $env:PsModulePath and execute it from there. Just to take parts out of the equation and see if it works that way.

Let me know what you find.

Cheers,
Dalmiro

Thanks Dalmiro. I reliased that we don’t actually need psake for this part of our CD process at all, so I’ve removed that dependency and it’s working very nicely now =) Please consider the request resolved.
