NullPointerException Error when importing a new API with system quotas

[gcornacchia]

APIM-CLI version

1.14.3

API-Management version

7.7.20211130

Bug description

When I try to import a new frontend api definition with system quotas (per operation) included in JSON file an error occurs.

Steps to reproduce

Consider the following zip file where you can find the frontend api definition in json format for apim-cli and relative swagger file.
PetStoreAPI.zip

1. import your API PetStoreAPI.json for the first time (the API must not yet exist on API Manager)

If I run the following import command:

> apim.sh API import -c PetStoreAPI.sjon -s myEnv -retryDelay 3000

I got the following log

If I run the import for the second time the API is correctly imported (quotas included).

Hi @gcornacchia,

I have fixed the issue, but when I reimport the same configuration, it is not throwing an errer saying no changes detected. Hence I am keeping the issue #475
