why the response is strange in wso2 - wso2

Question

I use postman to test
http://192.168.1.208:8090/jobsappName=sparkJoin001&classPath=com.mymoon.sql.SparkJoin
It's ok! It returns the message:
{
"status": "STARTED",
"result": {
"jobId": "3a47f931-f040-4e4a-a688-331f1918ae82",
"context": "6a171d9d-com.mymoon.sql.SparkJoin"
}
}
it's http status is 202!
I config in the wso2 esb and return some messages, but the browse shows the mixed message! It's stange!
The config is :
<api xmlns="http://ws.apache.org/ns/synapse" name="d" context="/dd">
<resource methods="GET" uri-template="/submit">
<inSequence>
<log level="full"/>
<payloadFactory media-type="text">
<format>{"uuid":"201456541","table": "aa/aa_table","condition":"names|91194185"}</format>
<args/>
</payloadFactory>
<send>
<endpoint>
<http method="POST" uri-template="http://192.168.1.208:8090/jobs?appName=CU&classPath=com.mymoon.ses.SparkCount"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<log level="full">
<property name="asdfsadf" expression="json-eval($.)"/>
</log>
<payloadFactory media-type="text">
<format>{"jobId":"$1", "table":"$2"}</format>
<args>
<arg evaluator="json" expression="$.result.jobId"/>
<arg value="test"/>
</args>
</payloadFactory>
<send/>
</outSequence>
</resource>
</api>
So I test http://192.168.1.101:8280/dd/submit . The browser shows such message.
{
"status": "STARTED",
"result": {
"jobId": "548e9590-e442-439f-9234-223bf5bf669e",
"context": "dd803c98-com.mymoon.ses.SparkCount"
}
}{"jobId":"548e9590-e442-439f-9234-223bf5bf669e", "table":"test"}
I hope message is this:
{"jobId":"548e9590-e442-439f-9234-223bf5bf669e", "table":"test"}
So I'm confused! Help me!Thanks!

i have tested using ESB 4.8.0. i have modified your API code as follows. I tested with mock service and its working. only change i made is change media-type json from text
<api xmlns="http://ws.apache.org/ns/synapse" name="d" context="/dd">
<resource methods="GET" uri-template="/submit">
<inSequence>
<log level="full"></log>
<payloadFactory media-type="json">
<format>{"uuid":"201456541", "table": "aa/aa_table", "condition":"names|91194185" }</format>
<args></args>
</payloadFactory>
<send>
<endpoint>
<http method="post" uri-template="http://demo2965385.mockable.io/test"></http>
</endpoint>
</send>
</inSequence>
<outSequence>
<log level="full">
<property name="asdfsadf" expression="json-eval($.)"></property>
</log>
<payloadFactory media-type="json">
<format>{"jobId":"$1", "table":"$2"}</format>
<args>
<arg evaluator="json" expression="$.result.jobId"></arg>
<arg value="test"></arg>
</args>
</payloadFactory>
<send></send>
</outSequence>
</resource>
</api>
response look as follows
{
"jobId": "3a47f931-f040-4e4a-a688-331f1918ae82",
"table": "test"
}
