CocoaPods proxy - additional source configuration of podspec lost

I’m using Nexus with CocoaPods (amongst other) and recently added Pod which original podspec source include extra attributes:

...
    },
    "source": {
        "http": "https://github.com/krzyzanowskim/OpenSSL/archive/1.1.1100.zip",
        **"type": "zip",**
**        "flatten": true**
    },
    "authors": {
....
    },
    "source": {
        "http": "https://*********/repository/cocoapods-proxy/pods/OpenSSL-Universal/1.1.1100/1.1.1100.zip"
    },
    "authors": {

But on podspec generated by Nexus while source url is updated correctly the other attributes are missing which results in that pod failing during the build.

Is there any workaround for this problem/bug or maybe plans to fix it?

This sounds like a bug, I’d suggest checking Issues · sonatype/nexus-public · GitHub to see whether it has been previously filed, if not create a new issue.
