Installshield: Copy file using powershell not working when running as Suite Action

[yBother]

I have a simple task that:

copy and replace an existing .json file on the target machine.

I am executing it as Event/Action in my Suite with elevated rights.

This is the  script:

try
{
$ProductName = "ravendb"
$Product = Get - WmiObject - Class Win32_Product | Where - Object { $_.Name - eq $ProductName}

if ($Product)
{
stop - service RavenDB
(Get - Service RavenDB).WaitForStatus('Stopped', '00:00:30')

$Folder = 'C:\RavenDB-4.2.x\Server'
Copy - Item - Path "settings.json" - Destination $Folder - force

start - service RavenDB
(Get - Service RavenDB).WaitForStatus('Running', '00:00:30')

exit(0)

}
else
{
exit(1)
}

}
catch
{
$StringValue = resolve - suitestring - StringId - Message
trace - suiteinfo - LogMessage $StringValue
exit(1)
}

Note that I tried to somehow print debug info to suiteinfo but I am not sure if that works.

Suite debug log says:

2-25-2023[01:26:47 PM]: Running event 'update-ravendb-settings'
2-25-2023[01:26:47 PM]: Engine: request for proxy handler, 0, 0

2-25-2023[01:26:57 PM]: Action 'update-ravendb-settings' returned status 0x00000000

But the file has actually not been overwritten. Service is being stopped/restarted though.

Note that calling the script manually works just fine!

Why is it, that the copy/replace does not work when calling in suite?
