Create Account returns id(nativeIdentity in the schema), it is not getting mapped

Basically it is not a valid JSON so your mapping is not working.

There is a similar post of resolving the issue, you have to write a afterOperation connector rule:

Webservice Connector - Create Account Operation - Empty Response - Identity Security Cloud (ISC) / ISC Discussion and Questions - SailPoint Developer Community
