How to use powershell syntax within a json file?

Question

I am trying to run a powershell command within a json file which is for cloudformation template. I am getting errors with anything after the pipe(|) symbol.

This is a new script that needs to work for our templates.

"commands": {
                        "UpdateAbsolutePath": {
                            "command": "powershell.exe -Command ((Get-Content -path D:\\Tomcat-8.0\\webapps\\lease_accelerator\\WEB-INF\\web.xml -Raw) -Replace \"LA-AWS-SU1-APP1\",\"LA-AWS-SU2-APP1\") | Set-Content -Path D:\\Tomcat-8.0\\webapps\\lease_accelerator\\WEB-INF\\web.xml"
                        }

I expect it to run fine, but I get the following error:

[DEBUG] No services specified
2019-06-05 13:49:01,572 [DEBUG] Running command UpdateAbsolutePath
2019-06-05 13:49:01,588 [DEBUG] No test for command UpdateAbsolutePath

Enclose the command within double quotes or add a ^ before the pipe symbol.

Some valid and non-valid examples:

> powershell -Command Write-Output "OK" | Out-String
'Out-String' is not recognized as an internal or external command, operable program or batch file.

> powershell -Command Write-Output "OK" ^| Out-String
OK

> powershell -Command 'Write-Output "OK" | Out-String'
'Out-String' is not recognized as an internal or external command, operable program or batch file.

> powershell -Command "Write-Output `"OK`" | Out-String"
OK

> powershell -Command { Write-Output "OK" | Out-String }
'Out-String' is not recognized as an internal or external command, operable program or batch file.

> powershell -Command "& { Write-Output "OK" | Out-String}"
OK

What's the meaning of the ^ symbol before the pipeline symbol?
