Azure VM PowerShell RUN Command not passing parameters

I am making an Azure CLI Run command call to a Windows VM, AZ VM run-command but cannot get the parameters to pass properly?

Command to call from Azure CLI:

az vm run-command invoke 
  --resource-group 'resgrpname' 
  --name 'hostname' 
  --command-id 'RunPowerShellScript' 
  --scripts "C:ScriptsStart_script.ps1" 
  --parameters "A=B"

When the PowerShell script runs, it executes correctly, appending to a file, but doesn’t accept the parameter. Code in the PS1 script:

param(
    [string]$SID
)

# Use the $param1 and $param2 variables in your script
date | Out-File -FilePath C:scriptsPowerShellLog.txt -Append
$A   | Out-File -FilePath C:scriptsPowerShellLog.txt -Append
" "  | Out-File -FilePath C:scriptsPowerShellLog.txt -Append

The output file shows the date correctly appended, but is otherwise blank, not capturing a value for the $A??

Has anyone seen this before? Anything obvious I can try?

I have tried just passing the commands and parameters inline as text, rather than calling a PS1 script, but invoke doesn’t handle that very well, and it would soon get unwieldy in a multi-command PowerShell script

    For your script to work, the parameter you pass in az vm run-command invoke has to match the name of the parameter in your Powershell script.

    Therefore, you either need to rename the parameter to $A or pass the parameter as SID = B

    You’re trying to pass a parameter $A to a powershell script using the az vm run-command command. However, it seems that the parameter is not being captured correctly in the script.

    To fix this issue, remove the --parameters argument in the az vm run-command command, and also change the parameter from $A to $SID as shown below

       SID='B'"

    Here is the update script.

    Start_script

    param(
    [string]$SID
)
date | Out-File -FilePath C:scriptsPowerShellLog.txt -Append
$SID | Out-File -FilePath C:ScriptsPowerShellLog.txt -Append
" "  | Out-File -FilePath C:ScriptsPowerShellLog.txt -Append```

    Command to call from Azure CLI:

     az vm run-command invoke --resource-group Aks-rg-test --name venkat-vm --command-id 'RunPowerShellScript' --scripts "C:ScriptsStart_script.ps1  SID='B'"

    Output:

    Once the above command is executed, the value of the SID parameter will be stored in the log file.
