Damaged or corrupted files calling S4HANA Public Cloud API_CV_ATTACHMENT_SRV

Dear Community, We’re migrating attachments from SAP Business ByDesign to SAP S/4HANA Cloud Public Edition using an ABAP application built with ABAP Development Tools (ADT) and developer extensibility. We retrieve attachment content from ByD using the API /sap/bc/srt/scs/doc/manageattachmentfolderin and parse the BinaryObject node. Here is a sample ByD response: fa163e37-0408-1fe1-aca6-ad4ddda00a67 JVBERi0xLjQKJeLjz9MKNiAwIG9iago8PAovVHlwZSAvWE9iamVjdAovU3VidHlwZSAvWE1hZ2UKL1dpZHRoIDEyNzUKL0hlaWdodCAxNjUwCi9Db2xvclNwYWNlIC9EZXZpY2VSR0IKL0JpdHNQZXJDb21wb25lbnQgOAovRmlsdGVyIC9EQ1REZWNvZGUKL0
