AWS PowerShell 4.0.2.0版本Get-IAMCredentialReport命令BUG求助

You’re definitely not the only one hitting this bug. Multiple users have reported identical behavior in AWS community spaces and the official AWS Tools for PowerShell repo—version 4.0.2.0 seems to break the -AsTextArray parameter for Get-IAMCredentialReport, spitting out metadata instead of the actual CSV lines, while 3.3 works as intended.

Here are practical fixes to resolve this:

• Roll back to version 3.3
  Since you know this version works flawlessly, it’s the fastest solution. Use these commands to swap versions (use AWSPowerShell.NetCore instead if you’re on the .NET Core module):

  # Uninstall the problematic 4.0.2.0 version
  Uninstall-Module -Name AWSPowerShell -Force
  # Install the confirmed stable 3.3 version
  Install-Module -Name AWSPowerShell -RequiredVersion 3.3 -Force
  

• Manually extract content from the MemoryStream
  If you can’t roll back right now, you can work around the broken parameter by directly reading the returned MemoryStream to get the CSV content:

  # Fetch the report object (which includes the MemoryStream)
  $credReport = Get-IAMCredentialReport
  # Convert the stream to a string, then split into an array (matching -AsTextArray's expected output)
  $streamReader = New-Object System.IO.StreamReader($credReport.Content)
  $csvContent = $streamReader.ReadToEnd()
  $textArray = $csvContent -split "`n"
  # $textArray now contains the CSV lines you'd expect
  

• Upgrade to the latest AWS Tools version
  AWS usually patches these kinds of issues in subsequent releases. Try updating to the most recent version and verify if the bug is fixed:

  Update-Module -Name AWSPowerShell -Force
  

  Note: Test this in a staging environment first to ensure your existing scripts don’t have compatibility issues with the updated module.

• Submit an official bug report
  If upgrading doesn’t resolve the problem, file a bug report with AWS. Be sure to include details like your PowerShell version, operating system, and exact steps to reproduce the issue—this helps their team diagnose and fix the bug quicker.
