WSO2: ESB: Passing data received, which is not in SOAP format, to a sequence is failing

Question

I have a REST API, (let's call it MYTESTAPI1), which invokes a third party API for some data. The third-party API returns the data in the following format.

After the call, when a new sequence is invoked in the above API, it works fine.

<wd:Report_Data xmlns:wd="Project_Export">
<wd:Report_Entry>
<wd:referenceID>PR00001</wd:referenceID>
<wd:projectName>
Test Project1
</wd:projectName>
<wd:Inactive>0</wd:Inactive>
<wd:Cost_Center_group>
<wd:Cost_Center_ID>CG1</wd:Cost_Center_ID>
</wd:Cost_Center_group>
<wd:Research_Budget_Remaining>0</wd:Research_Budget_Remaining>
<wd:Currency wd:Descriptor="AUD">
<wd:ID wd:type="WID">8a96ee707a264afe888d90ef93253305</wd:ID>
<wd:ID wd:type="Currency_ID">AUD</wd:ID>
<wd:ID wd:type="Currency_Numeric_Code">036</wd:ID>
</wd:Currency>
</wd:Report_Entry>
</wd:Report_Data>

But, when I call the MYTESTAPI1 REST API, from another proxy service(which is in a different CAR file), then it gives the following exception. Any help would be really helpful. If I return the result without passing to the sequence, then it does not give an error.

It seems like the SOAP envelope tags are removed from the response due to some reason. Since you have a sequence, that might cause this. Would you be able to provide the sequence logic as well? — menaka_
<?xml version="1.0" encoding="UTF-8"?> <sequence name="testseq" trace="disable" xmlns="ws.apache.org/ns/synapse"> <log> <property name="msg" value="hi hello"/> </log> </sequence> — ravi
The third party API returns message which is not in SOAP format, cant we use that message for further mediation? — ravi

I believe you are using an address endpoint. Please switch to an HTTP endpoint to resolve the issue.
