Why is Powershell ISE showing errors that Powershell console does not show?

Question

I'm running exactly the same script.ps1 file in a Powershell ISE (manually loading the script and pressing F5) and in a Powershell console (executing the script file). They both work but ISE shows errors that the console does not. Why?

The code is:

git push origin master
Write-Host "lastExitCode: $lastExitCode Last command was successful: $?"

This code output this error in the ISE:

git.cmd : Initializing to normal mode
At E:\script.ps1:28 char:4
+ git <<<<  push origin master
    + CategoryInfo          : NotSpecified: (Initializing to normal mode:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

Initializing to normal mode

Everything up-to-date

lastExitCode: 0 Last command was successful: False

And this in the console:

Everything up-to-date
lastExitCode: 0 Last command was successful: True

You can see that the success status is not the same also.

Answer 1

as shown in this Stackoverflow answer to prevent git push to print to STDERR the solution is to call the command witn --porcelain option.

then, calling

git push origin master --porcelain

output goes all to STDOUT

Answer 2

So, the example below case have any error , this command -q 2>&1 | %{ "$_" }` will nullifying the result of errors.

A solution and use: git push -q 2>&1 | %{ "$_" }
