           Name='Entra', Options={ CorrelationId=a9a7d5d0-d40f-4a97-9b5d-48e5b42546b6, Actor=adm-mafl-server } and no default auth session configured.""
Attempts : 1

Steps to Reproduce

0. You need some entraAccess token and AD Credentials first (adCred because for next steps not mentioned below).
1. Workflow definition

@{
    Name           = 'Offboarding Stage 1'
    LifecycleEvent = 'Leaver'

    Steps          = @(
        @{
            Name = 'Entra - Block account'
            Type = 'IdLE.Step.DisableIdentity'
            With = @{
                AuthSessionName = 'Entra'
                IdentityKey = '{{Request.IdentityKeys.sAMAccountName}}@nanotempertech.com'
                Provider = 'Entra'
            }
        }
    )
}

2. Request is

$request = New-IdleRequest -LifecycleEvent 'Leaver' -IdentityKeys @{
    sAMAccountName = 'max.power'
} -DesiredState @{
    OffboardingDate = '2026-02-30'
} -Actor $env:USERNAME 

3. Setting up provider and auth Sessions

$authSessions = New-IdleAuthSession -SessionMap @{
    @{ AuthSessionName = 'AD' }  = @{ AuthSessionType = 'Credential'; Credential = $adCred }
    @{ AuthSessionName = 'Entra' } = @{ AuthSessionType = 'OAuth'; Credential = $entraAccessToken }
    @{ AuthSessionName = 'EXO' } = @{ AuthSessionType = 'OAuth'; Credential = $entraAccessToken }
}

# Creating Providers
$providerAD = New-IdleADIdentityProvider
$providerEntra = New-IdleEntraIDIdentityProvider
$providerEXO = New-IdleExchangeOnlineProvider
$providers = @{
    AD = $providerAD
    Entra = $providerEntra
    EXO = $providerEXO
    AuthSessionBroker = $authSessions
}

4. Plan and Execution

$plan = New-IdlePlan -WorkflowPath $leaverWorkflow -Request $request -Providers $providers
$result = Invoke-IdlePlan -Plan $plan
$result.Status
$result.Steps | Select-Object Name, Status, StartedUtc, FinishedUtc

Expected Behavior

Invoke-IdlePlan should find defined AuthSessions.

Actual Behavior

AuthSession cant be found.
This behavior also remains if only one element is within SessionMap.
