I think Alexandru Florescu would be best to answer this, but I think the problem might be because of this line:

https://github.com/RWS/groupshare-api-powershell-toolkit/blob/912c2a5671fa7ae27501f8ff081ffa936f030801/Modules/ResourcesHelper/ResourcesHelper.psm1#L2263

I think this might be only waiting while the status is "Queued", but doesn't wait for the "InProgress" status.  So when a background task transitions from "Queued" to "InProgress" to "Done", the function exits the loop as soon as it's no longer "Queued" and then tries to download the file while it's still being processed.

So you could change the condition to check that the status is neither "Queued" nor "InProgress", or better yet, wait until it's "Done".  

The task statuses according to the documentation are:

1 - Queued
2 - InProgress
4 - Canceled
8 - Failed
16 - Done

Find them here:

https://github.com/RWS/groupshare-api-powershell-toolkit/blob/912c2a5671fa7ae27501f8ff081ffa936f030801/Modules/BackgroundTaskHelper/BackgroundTaskHelper.psm1#L39

So try changing your copy of the ResourcesHelper.psm to this (for example):

while ($status.Status -ne "Done")
{
Start-Sleep -Seconds 2;
$status = Invoke-RestMethod -Uri $taskUri -Headers $taskHeaders
}

Or... just add a short sleep function in your powershell script to give the export function time to complete its task before actually getting the file:

Start-Sleep -Seconds 30 (for example)

But Alexandru can confirm for sure!

Hi Paul!

I've changed the  Get-ExportFile function as you suggested:

from

while ($status.Status -eq "Queued")

to

while ($status.Status -ne "Done")

It works! Thank you!
