SAP Cloud SDK for JavaScript: unable to post entry with a date field


I am trying to create a material document header using the following request payload which has postingdate as mandatory field.

MaterialDocumentHeader {
  goodsMovementCode: '01',
  postingDate: '2020-04-11T10:00:00',
  toMaterialDocumentItem: [
  // not relevant 

When I try to post, console says the following. Seems like issue with Datetime conversion.

TypeError: momentInstance.unix is not a function
    at Object.momentToEdmDateTime (C:\Users\xxx\my-sdk-project\node_modules\@sap-cloud-sdk\core\dist\payload-value-converter.js:82:36)

Anyone faced this issue before? Or am I doing anything wrong?

    Hello Tejaswi,

    when I look at the typescript definition of the document header it looks like:

    postingDate?: Moment;

    So the posting date should be a moment instance. Could you try to create a instance like described here:

    Let me know if this helps.
