Logic App Standard Inline C# Aktion kann AES CBC mit PKCS7 nicht entschlüsseln (funktioniert in der Funktion App) ⇐ C#

[Anonymous]

Ich versuche, in einer Logik-App-Standard-Inline-C#-Aktion zu entschlüsseln, aber der Code, der in einer Funktions-App einwandfrei funktioniert, fällt in logischen Apps fehl. < /p>

Code: Select all

Problem
< /code>

  Der AES-Schlüssel wird in einem Azure-Taste als Basis 64-kodierter String
gespeichert (32 Byte → aes-256). Verschlüsselte Nutzlast.InvokeFunctionFailed
The function 'CSharp_wf-infringement-process-transaction_execute_csharp_script_code.csx'
failed with the error 'Exception binding parameter 'context'' when executing.
Please verify function code is valid.
