I am trying to use catalog producer of AEM in conjunction with InDesign server to create pdf. I have downloaded a sample indd file from internet and imported it in catalog template in AEM assets. Now I am trying to create a page in AEM using article https://docs.adobe.com/docs/en/aem/6-1/administer/integration/catalog-producer.html. In this, when I reach "define mapping", it gives me error "failed to create media asset". Can anybody please help me understand why this issue might be coming.
Note: I am not using Geometrix indd file but a sample indd file. Do indd file needs to be of a specific specification and having properties.
