PI REST Receiver http_result problem with json objects

[pi_guy]

Here is a tough one.

I have a REST receiver with custom error handling. When the HTTP response is not 200, I am getting a json with the error description in an object i.e. {"errorCode":"Generic","errors":{"vendorId":"SKYPAI not exist."},"message":"Bad request"}. My custom response looks like:

<?xml version="1.0" encoding="UTF-8"?>

<data>

{http_result}

</data>

For some reason, PI only converts the first part to XML and disregards the object completely so I get:

<data><errorCode>Generic</errorCode></data>

And I cannot fetch the rest of the json whatever I try to do.

Any ideas? I am on 7.5 latest SP and patches.

Thanks

I managed to work around this by setting the "Add Wrapper Element" flag. I still think there is some kind of bug there that has to do with JSON to XML conversion of objects, but it's working now. (Of course I now have to remove the wrapper in JAVA mapping or XSLT, but that's easy enough)
