Fix token refresh failure due to missing TenantID scope

[Copilot]

Authentication succeeds initially but all subsequent requests fail with AADSTS900144: The request body must contain the following parameter: "client_id" after token expiry.

Root Cause

Invoke-CIPPPreFlightCheck.ps1 uses unscoped $TenantID instead of $script:TenantID when refreshing expired tokens, passing null to the OAuth endpoint.

Changes

CIPPAPIModule/private/Invoke-CIPPPreFlightCheck.ps1

• Line 62: TenantID = $TenantID → TenantID = $script:TenantID

# Before
$request = @{
    CIPPClientID     = $script:CIPPClientID
    CIPPClientSecret = $script:CIPPClientSecret
    CIPPAPIUrl       = $script:CIPPAPIUrl
    TenantID         = $TenantID  # ❌ Resolves to null
}

# After
$request = @{
    CIPPClientID     = $script:CIPPClientID
    CIPPClientSecret = $script:CIPPClientSecret
    CIPPAPIUrl       = $script:CIPPAPIUrl
    TenantID         = $script:TenantID  # ✅ Preserves value from Set-CIPPAPIDetails
}

Aligns with existing pattern in Connect-CIPP.ps1 which correctly uses $script:TenantId.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.cipp.app
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
