WSProxy: nested fault error trying to call a SOAP service

Question

I'm getting an error trying to call a SOAP service, the client provided a "sample" of the body content, however, with all the reshaping of that the best that I can get on an online XML validator is the following error:

WSProxy: nested fault: XML parse failed: libxml error: : level: 2, code: 201, file: none, line: 14, str1: "bo", str2: "concnt", str3: "", int1: 0, int2: 34, message: Namespace prefix bo on concnt is not defined

the request body is:

        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:srt="http://external_svc.org/F6/wallet/bo">

        </soapenv:Envelope>

anybody can see what's the error here?

Answer 1

The namespace-prefix: bo has not been declared.

Depending on what the namespace-uri for bo should be, your soapenv:Envelope should look like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:bo="theUriForTheBoPrefix" xmlns:srt="http://external_svc.org/F6/wallet/bo"
