[I-am-Victor]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

if i paste my input into my script, it shows error.
however, if i type them line by line, there wont be any error and runs smoothly.
this only happens in debugging(set breakpoints).

Hi, sorry about this, do you have viable workaround? I think we'd need a more minimal reproduction to figure out this bug.

bugs.txt

[string[]]$domains = $null
while ($true) {
    $inp = Read-Host
    if ([string]::IsNullOrEmpty($inp)) {
        break
    }
    $domains += $inp
} #stop until a blank line.
for ($i = 0; $i -lt $domains.Count; $i++) {
    [string]$check = q.exe $domains[$i] A `@tls://dns.google
    Write-Output $check;
}

If you copy bugs.txt and paste it in the script, the error shows.
This is the console shows when debugging:

PS C:\Users\Victor\Other\Programs> Write-Host "**$($domains[$i])**"
**github.com                                   **
PS C:\Users\Victor\Other\Programs> q.exe $domains[$i] A `@tls://dns.google
PS C:\Users\Victor\Other\Programs> q.exe github.com                                    A `@tls://dns.google
github.com. 1m A 20.205.243.166

paste it in the script
can you be more specific? I can't reproduce, pasting into the PSES terminal works just fine for me.
