ServerlessError: Documentation part already exists while deploying Serverless AWS apigateway

[rsolank1]

I am getting [ServerlessError: Documentation part already exists] while deployment when I have updated the version in documentation object from version:"8.0.2" to version:"9.0.1".

But it succeed when run deployment again by updating version in documentation object from version:"9.0.1" to version:"9.0.2".

`

custom:
  documentation:
    api:
      info:
        version: "9.0.2"
        title: "Mock APIs"
        description: "Mock Apis for my new project"

I am unable to understand how serverless-aws-documentation versioning is working while deploying on API Gateway.

It doesn't matter what limit we set for the getdocumentationparts because AWS does not return more than 500 records per single time.
so when second time we run deployment remaining part also get deleted hence it works in second time.
also its not dependent on our versioning, because documentation version is the hashcode of whole custome_documentation object and documentation parts. That's how it compares the versions.
