Thanks for reporting @sachinlionel. Could you provide a full example that we could use to reproduce the problem, including the full error traceback? Thanks.

Without additional error information, and acknowledging that STACObjectType.ITEMCOLLECTION no longer exists (#430), I'm closing as not planned.
