Import-Clixml Error when opening Terminal

[Irtiza90]

Current Behavior

I get an error randomly when i open the terminal, it only gives an error at launch.

Error Message:

(yesterday, when i checked i received this error message)

Import-Clixml: Key for dictionary entry is not specified. Line 104, position 7.
InvalidOperation: Index operation failed; the array index evaluated to null.
Import-Clixml: 'Element' is an invalid XmlNodeType.
InvalidOperation: Index operation failed; the array index evaluated to null.
InvalidOperation: Index operation failed; the array index evaluated to null.

(this error i just received)

Import-Clixml: Value for dictionary entry is not specified. Line 109, position 21.
InvalidOperation: Index operation failed; the array index evaluated to null.
InvalidOperation: Index operation failed; the array index evaluated to null.
InvalidOperation: Cannot index into a null array.
InvalidOperation: Cannot index into a null array.
InvalidOperation: You cannot call a method on a null-valued expression.
InvalidOperation: You cannot call a method on a null-valued expression.

Steps to Reproduce (for bugs)

Opening the terminal randomly gives the error, sometimes i see the error, othertimes i don't.

The error doesn't seem to be causing any issues with the terminal, most probably just a visual error.

Your Environment

OS Version: Windows 10(22H2)
Terminal: Powershell 7.4.1
I'm using ohmyposh and Terminal-Icons powershell modules

We would want to see the output from the below after the error.

get-error -last 2

Additionally, does the same error happen when you load PowerShell Core with no profile? You launch with pwsh -noprofile.

Lastly, it is possibly related to #121.

If you don't mind 1 second delay below profile works for me with a 2x2 split terminal startup with pwsh 7.4.5

oh-my-posh init pwsh --config '<your-config>.json' | Invoke-Expression

$WarningPreference = 'SilentlyContinue'
$ErrorActionPreference = 'SilentlyContinue'

Import-Module -Name Terminal-Icons

# set back to default values with a 1 second delay
Start-Sleep -Seconds 1
$WarningPreference = 'Continue'
$ErrorActionPreference = 'Continue'

Similar error for me:

import-module terminal-icons
Import-Clixml: Value for dictionary entry is not specified. Line 603, position 40.

When exploring these lines in Terminal-Icons.psm1:

(Get-ChildItem $userThemePath -Filter '*_icon.xml').ForEach({
    $userIconTheme = Import-CliXml -Path $_.FullName
    $userThemeData.Themes.Icon[$userIconTheme.Name] = $userIconTheme
})

I found that $userIconTheme tracked back to $basePath = [Environment]::GetFolderPath('ApplicationData').

This location did not contain the expected xml files, thus why this error was occuring.

My workaround to address this for me was:

1. Launch cmd.exe
2. Run pwsh -noprofile
3. Run Import-Module terminal-icons

The above steps caused the module to create a: AppData\Roaming\powershell\Community\Terminal-Icons and the module is now able to be imported in Terminal.
