Null Pointer Exception when creating a new version of an API

[charithjayasanka]

Description

When a new version of a migrated API is created, (from APIM-2.1) The following exception is thrown.

For this, instead of committing half changes before accessing the swagger details, it's better to validate swagger information before committing anything in the flows, such as creating a new version, update API , and other flows. And need to check if the info object is present at the start of the create new version flow. If the info object is not there, better to throw an error by blocking the create new version flow. Similarly, it needs to perform this check for API update flows, and so on.
