Jasper Server Rest API Create Json DataSource Error 500

[lzhaogoh]

Hi, I m trying to make a POST request to create Json DataSource in Jasper Server. 

The Content-Type is set to application/repository.customDataSource+xml already.

But somehow I receive error 500 upon sending this request. May I know where I did wrong?

<customDataSource>

    <serviceClass>com.jaspersoft.jasperserver.api.metadata.jasperreports.service.ReportDataAdapterService</serviceClass>

    <label>MYMY</label>

    <uri>/TestAPI</uri>

    <dataSourceName>MYMY</dataSourceName>

    <description>TestTest</description>

    

<properties>

    <property>

        <key>language</key>

        <value>json</value>

    </property>

    

    <property>

        <key>fileName</key>

        <value>repo:/TestAPI/myData.json</value>

    </property>

    

    <property>

        <key>selectExpression</key>

        <value>data</value>

    </property>

</properties>

</customDataSource>
