format exception causing scripthost to continually restart

Hi,

A bunch of my jobs are causing the following error to occur, which is sending the scripthost into a cycle of constantly restarting:

Unfortunately, I haven’t been able to narrow it down to a specific job and the error isn’t super helpful. Any idea what might be triggering this?

Thanks, James

@mathewc in case you’re interested, here was the response to the issue I posted:

@jamesdixon , refer to the breaking change log, originally the SDK only support a flag which indicates if the queue message should be encoded/decoded (base64 encoding). But we found that’s not enough and not extensible. So we decided to introduce the encoding/decoding interface and provided some built-in encoders. For why we change the default encoding behavior from base64 encoding to XML encoding, it’s because XML encoding will have smaller payload size for most scenarios. Please let me know if this makes sense.

Closing since this appears to be a Azure Node SDK issue
