Rest: Invalid white space character (0x1a) Error

[former_member312853]

Hi Experts,

While performing testing <Proxy to Rest> synchronous scenario, i am getting escape characters in response payload which causing the below error.

MP: exception caught with cause java.lang.RuntimeException: com.ctc.wstx.exc.WstxIOException: Invalid white space character (0x1a) in text to output (in xml 1.1, could output as a character entity)

Could you please suggest, how to handle the scenario.

Regards,

Manoj Kumar

Assuming you have PI and use Axis adapter: You would probably need to make sure either the sender will not send this whitespace or you will need to clean things beforehand, e.g. with a java mapping?

Where exactly are you getting this white space?

It is inside some feild?

Hi Khusal,

In response payload, one of the field contains the special characters.

Hi Manoj,

Is the whitespace needed at the reciever end is one thing you need to see.

Depending on this there can be 3 solutions to this.

Please check whichever works fine for you.

1. Ask the sender to trim the whitespace itself.
2. Use JAVA mapping before message mapping to trim the feild or enclose the same in <CDATA> TAG
3. Use graphical mapping to enclose the field in <CDATA> TAG.

Khusal.

Hi Kushal,

It required at receiver system side and confirmed it has to handle in PI side.

i am getting, JSON file as response from receiver system where REST adapter unable to convert it to XML file due to Special characters.

Hi Manoj,

I would suggest developing a JAVA mapping for converting JSON to XML,

when you are converting that particular field add <!CDATA> Tag for the same.
