FortiSOAR check readiness upgrade to 7.6.2 fails to complete due to missing entry

Trying to upgrade from 7.6.1 to 7.6.2. Getting below message

Entry of version 7.6.1 not added to upgrade_path.json file. To perform this operation for 7.6.2 version, contact administrator.

Checked for the file named upgrade_path.json but could not find this file on the system. 

Any help is appreciated.
