Received non-all-whitespace CHARACTERS or CDATA event in nextTag - soap

Question

I am using web service consumer(1.6.9) in Mule4 and triggering the external soap service, the external service is returning SOAP FAULT and below is the SOAP fault which I am getting as below
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<soapenv:Body>
<soapenv:Fault>
<faultcode>Internal Server Error</faultcode>
<faultstring>Unexpected close tag
</urn:UniqueName>; expected
</urn:UniqueNam>
at [row,col {unknown-source}]: [40,54]
</faultstring>
<Detail>Invalid incoming request /Buyer/soap/C133/X-T/testPull?null</Detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
but Web service consumer in mule is returning the below error:
Caused by: com.ctc.wstx.exc.WstxParsingException: Received non-all-whitespace CHARACTERS or CDATA event in nextTag()
Please let me know what is the issue, it seems web service consumer is throwing the above error while parsing the above soap fault.

Answer 1

It seems to be complaining that the SOAP fault response is not valid XML because of this line:
</urn:UniqueNam>
at [row,col {unknown-source}]: [40,54]...
</faultstring>
Note how the text is between </urn:UniqueNam> and </faultstring>. That's not valid in XML. There should be an XML tag or nothing there instead of plain text.
