SOAP to JSON Conversion resulting Internal server error

Question

Hi,

I am trying to convert soap to JSON in the outbound policy, it's basically the policy generated while importing the WSDL for some reason it just does not work. I also tried body.Envelope.Body.someResponse.someName but no use, I can confirm that backend is responding HTTP 200 and the SOAP response is as expected. Please suggest the best course of action. Here is my outbound policy.

<outbound>
	<base />
    <choose>
       	<when condition="@(context.Response.StatusCode < 400)">
           	<set-body template="liquid">
               	{
					"Name": {{body.envelope.body.someResponse.someName | Replace: '\r', '\r' | Replace: '\n', '\n' | Replace: '([^\\](\\\\)*)"', '$1\"'}} }}
                 }
			</set-body>
		</when>
		<otherwise>
			<set-variable name="old-body" value="@(context.Response.Body.As<string>(preserveContent: true))" />
                <set-body template="liquid">{
            		"error": {
                	"code": "{{body.envelope.body.fault.faultcode}}",
                	"message": "{{body.envelope.body.fault.faultstring}}"
            		}
        		}</set-body>
		</otherwise>
	</choose>
</outbound>

Vijay Akula Thanks for sharing the additional details. I have tested the sample policy snippet you shared with echo endpoint [http://echoapi.cloudapp.net/api/resource] and didn't produce any issue. Here are the details:

Output:

Code snippet:

<outbound>
        <set-variable name="response-body" value="@(context.Response.Body.As<string>(preserveContent: true))" />
        <set-body template="liquid">{
            		"error": {
                	"code": "{{body.envelope.body.someResponse.SomeName}}"
            		}
        		}</set-body>
        <base />
    </outbound>

I understand you may not be able to share the full sample request, response or exact policy info. Make sure to validate the casing such as fault, faultcode in the actual response.
