Hi, I am assisting a group that is insisting on using postman as a unit - development tool so my regular programming IDE's won't help. I provided a working mutation that adds a document without content, per IBM guide a second call/step is made for the multi part content upload which returns an error. Now in our regular WSI APIs content must accompany the create document, I get it but Graph is different.  Most likely this is a misunderstanding or lack of knowledge in setting the content within postman.  Is there anyone in this group that has used postman with graph to upload a document with content to P8 that can share the 'how to' to get this done?  Much appreciated!!
