Null key error while setting up custom Chocolatey package

Question

I'm trying to create a custom Chocolatey package that will use an msi file from a file share and I'm receiving the error below. I've be able to troubleshoot most of the error during this process, but I can't figure this one out.

Does anyone know how to solve this issue or know what I could do to debug the issue?

Error

ERROR: A null key is not allowed in a hash literal.
The install of ciscojabbertest2 was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\ciscojabbertest2\tools\chocolateyinstall.ps1'.

Below is a copy of my nuspec file and my chocolateyinstall.ps1 file.

I suspect that the error that you are seeing is due to the undefined variable $file. As a result, you are getting a key in the hash literal that doesn't have any value.

Change it to the following:

$ErrorActionPreference = 'Stop';
$toolsDir        = "$(Split-Path -parent $MyInvocation.MyCommand.Definition)"
$fileLocation    = '\\WIN-5LEH3K6JCM3\Software_Test\CiscoJabberSetup.msi'

$packageArgs = @{
  packageName    = $env:ChocolateyPackageName
  unzipLocation  = $toolsDir
  fileType       = 'MSI'
  file           = $fileLocation

  softwareName   = 'Cisco Jabber*'

  checksum       = 'A027601E0975339286EEECF593D83FF71FA64902B46A8F10F93B5E63663A215F'
  checksumType   = 'sha256'

  silentArgs     = "/quiet CLEAR=1"
  validExitCodes = @(0, 3010, 1641)
}
