A4SWIFT on BizTalk: Generating a valid MT103; How to understand why a message isn't being generated?

问题

We're working on using BizTalk generate a valid SWIFT message (initially MT 103) and dropping it onto an endpoint. However, we're struggling to generate a valid message.

(Similar, but different question, at this StackOverflow post. I broke the questions up because they are materially different.)

Given a populated A4SWIFT MT103 schema (namespace: http://schemas.microsoft.com/BizTalk/Solutions/FinancialServices/SWIFT/Categroy1/MT103), we're passing that through the SWIFT Assembler on a Pipeline, out of which we get a "flat" SWIFT MT 103 message.

We get a SWIFT message like that below (obviously false):

{1:F01ABCDEFGXAXXX0000000000}{2:I103ABCDEFGHXXXXN}{3:{108:143136}
:20:ABCDEF123456
:23B:CRED
:32A:170607USD500,1
:33B:USD500,1
:50F:/0000000000
Bible Baggins
1 Bag End
Hobbiton
ME1
:53A:/00000000
ABCDEFGXXXX
:57A:ABCDEF
:59F:/00000000000000
CashYourJewelleryFast.com
:71A:OUR
-}

Notice that Block 3 hasn't been terminated correctly and that Block 4 doesn't start correctly.

I'm missing the characters: }{4:

Dijkgraaf asked for the original XML. This is shown below (anonymised as best as I can to match the example):

I've checked the generated MT 103 message with known valid MT 103 messages generated in other systems and I'm confidence the details are present and in the correct format.

I suspect BizTalk/A4SWIFT have a bit of a fit when something is wrong and generates a half-created message.

Is there something I am missing? Where can I find actual errors associated with this, as opposed to just the counts? I can generate <UnparsedMessages /> and can route errors around based on the promoted properties but they don't contain any useful information.
