Transformer Error Connecting to Azure

[bksams]

Hi, I'm very new to developing on Mirth. My previous experience has just been monitoring. I'm trying to connect to an Azure queue and I'm having some problems. I would greatly appreciate any help. Here's the error when I tried to send a message.

@bksams , while this isn't the forums site, the forum etiquette mostly applies, see https://forums.mirthproject.io/articles/177082-forum-etiquette. In particular, post the full code, not just the error (bullet 8 from that link).
