WSO2：将CSV消息转换为json wso2 esb。在prolog中出现意外字符'“'（代码34）失败;预期'

Question

我试图使用数据映射器将csv转换为json。以下是我写的代理服务。

<?xml version="1.0" encoding="UTF-8"?>
<proxy name="csvtojson" startOnLoad="true" transports="http https vfs" 
xmlns="http://ws.apache.org/ns/synapse">
<target>
<inSequence>
<property expression="$body/*[1]" name="body" scope="default" type="OM"/>
<log level="full">
<property name="PropertyName" value="Message tobe fed to mapper"/>
</log>
<datamapper config="gov:datamapper/csvtojsonmapping.dmc" 
inputSchema="gov:datamapper/csvtojsonmapping_inputSchema.json" 
inputType="CSV" 
outputSchema="gov:datamapper/csvtojsonmapping_outputSchema.json" 
outputType="JSON"/>
<log level="full">
<property name="property_name" value="aftermapping"/>
</log>
<property name="ContentType" scope="axis2" type="STRING" 
value="application/json"/>
<log description="" level="full">
<property name="property_name" value="msgpropertyset as json"/>
</log>
<send>
<endpoint>
<http method="post" uri-template="https://www.google.com/"/>
</endpoint>
</send>
</inSequence>
<outSequence/>
<faultSequence/>
</target>
<parameter name="transport.PollInterval">1</parameter>
<parameter name="transport.vfs.FileURI">file:///tmp/in</parameter>
<parameter name="transport.vfs.ContentType">text/csv</parameter>
<parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
<parameter 
name="transport.vfs.MoveAfterFailure">file:///tmp/failure</parameter>
<parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
<parameter name="transport.vfs.Build">false</parameter>
<parameter name="transport.vfs.FileNamePattern">.*.csv</parameter>
<parameter name="transport.vfs.MoveAfterProcess">file:///tmp/out</parameter>
</proxy>

已经包含在axis2.xml文件中的两个下面：

执行服务时，我收到以下错误：
