This issue resolved.

One of the document had comments before the beginning of the yaml document (---). After fixing that able to generate genesis bundle.

Hi Naga, a new set of reference manifests have been added to the airship-treasuremap project.  Can you please have a look at those, and compare your manifests to what’s up there?  I’m not familiar with that error in this context, but it looks to be related to loading schema documents from your manifest sets.  I suspect comparing to a known-good set of manifests (including schema docs and references to those schemas) may help.

Thanks,
