Used below extract variable configuration xml:

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="Extract-Variables-1">
    <DisplayName>Extract Variables-1</DisplayName>
    <Source>calloutResponse.content</Source>
    <JSONPayload>
      <Variable name="latitude" type="string">
            <JSONPath>$.division.physics</JSONPath>
        </Variable>
    </JSONPayload>
    <VariablePrefix>apigee</VariablePrefix>
</ExtractVariables>
Got below Error: Invalid char ' ' at line 1 Not sure where is the issue , please advice.?
