Mobile First 7.1 SOAP Adapter failed to read response - soap

Question

I have used IBM MobileFirst Studio V7.1 - Service Discovery wizard option and created a SOAP adapter from a application WSDL file. The Service Discovery procedure correctly creates the MobileFirst adapter in the MFP Studio.
The sample message payload is as follows.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:fet="http://siebel.com/asi/Fetch Account Info">
<soapenv:Body>
<fet:ExecuteFetchAccountInfo_Input>
<fet:Object_spcId>1-6U8KAR</fet:Object_spcId>
</fet:ExecuteFetchAccountInfo_Input>
</soapenv:Body>
</soapenv:Envelope>
Now, using the adapter testing option in the MobileFirst Studio, the following JSON payload are being passed in the dialog window
params:
{"ExecuteFetchAccountInfo_Input":{"Object_spcId":"1-6U8KAR"}}
But I get the following error when I call the adapter
{
"errors": [
"Runtime: Failed to read the HTTP response to: \/eai_enu\/start.swe?SWEExtSource=WebService&SWEExtCmd=Execute \njava.io.EOFException: Unexpected end of ZLIB input stream"
],
"info": [
],
"isSuccessful": false,
"warnings": [
]
}
Also when I tried to check the log files. I was able to capture the request and response.

By looking at the response it says the response if Ok but it is unable to read it. Please help if I need to set-up something extra to read the response.

Answer 1

It turns out that there was a defect here that needed to be fixed. The APAR number is PI67417 and it can be downloaded from Fix Central.
Once you've applied the iFix, you'll also need to add "Accept-Encoding: identity" to your adapter call. That should resolve your issue. If it doesn't please let me know.

Answer 2

Since this is working in SOAP UI but fails in the adapter, it may indicate a product defect. Please open an IBM PMR and provide your files for reproduction by the development team.
