Циклы учетных данных в PowerShell

Question

Я работаю над проектом PowerShell / RabbitMQ, следуя этому учебнику , и обнаружил проблему при попытке подключиться к слушателю RabbitMQ.

Invoke-RestMethod : {"error":"bad_request","reason":"[{key_missing,ackmode}]"}

Мне удалось это исправитьнабрав эту строку кода в файле GetMessage.ps1:

"ackmode" = @("ack_requeue_true", "ack_requeue_false")[[bool]$Remove]

Теперь это работает, и каждый раз, когда я выполняю запрос / процедуру, я получаю сообщение на RabbitMQ, сообщающее мне, что произошло.

Основная проблема заключается в том, что PowerShell запрашивает учетные данные для каждой строки в результате SQL, и если я еще ничего не выполнил, он по-прежнему запрашивает учетные данные каждые 3-5 секунд, даже если я сохранил их, используя:

$Credential = Get-Credential
