Custom Compliance Policy Error 65009 in Microsoft Intune

[rababb]

I created a custom compliance policy that searches for a specific registry key to check device compliance however, I am getting the following error 65009 (Invalid Json for the discovered setting). I checked the Json script in JSON Lint but there is no syntax error. I will add the PowerShell script and Json file below.

PowerShell script:

# Define the registry path and value name

$registryPath = "HKCU:\SOFTWARE\TestCompliance"

$registryValueName = "TestValue"

# Check if the registry value exists

$registryValue = Get-ItemProperty -Path $registryPath -Name $registryValueName -ErrorAction SilentlyContinue

# Determine compliance status based on the registry value

$isCompliant = $null -ne $registryValue.$registryValueName

# Create a hash table with compliance details

$hash = @{

    RegistryPath = $registryPath

    ValueName = $registryValueName

    IsCompliant = $isCompliant

}

# Return the hash table as a compact JSON string

return $hash | ConvertTo-Json -Compress

Json File:
