Missing JSON code in party.postman for iMIS Cloud

Hi there,

I download the Party iMISRESTCollection for iMIS Cloud version from GITHUB using this link https://github.com/Advsol/iMISRESTCollection/blob/master/EndpointCollections/iMIS%20Cloud/20.3.44/Party.postman_collection.json.

I try to find the way to use the Post method in to create a party but it seems the JSON syntax missing and it cause the error when I click sent button in Postman.
The please see the error in this screenshot: https://ibb.co/Mp1mFFP

Thank you for your help.
