but, when use below coding, there is no error.


{"RetrieveHeadlineML_Request_1":{"HeadlineMLRequest":{"Direction":"Newer","EndTime":"2022-06-02T17:50:16","Filter":[{"MetaDataConstraint":{"Value":{"Text":"LZS"},"class":"topics"}},{"MetaDataConstraint":{"Or":{"Value":[{"Text":"CLN"},{"Text":"CDS"},{"Text":"CMN"}],"Value_typehint":["Value","Value","Value"]},"class":"products"}},{"MetaDataConstraint":{"Or":{"Value":[{"Text":"PBOC"},{"Text":"PLCY"},{"Text":"CEN"},{"Text":"MCE"},{"Text":"FED"}],"Value_typehint":["Value","Value","Value","Value","Value"]},"class":"topics"}},{"FreeTextConstraint":{"Or":{"Value":[{"Text":"全球汇市"},{"Text":"中国汇市"}],"Value_typehint":["Value","Value"]},"where":"headline"}}],"MaxCount":50,"MaxCountPerFilter":false,"StartTime":"2022-06-01T17:50:16","TimeOut":30,"maxCountWorkAround":false}}}

    Hi @tao.su ,

    Could you try changing the value in the 'where' parameter from 'Headline' to 'headline'?

    I've tried and no error is found. However, if you have any further questions regarding the content, The best approach is to reach out to the RKD support directly to RKD support.
