Object Diagram does not work properly with "packages"

[RaffaelGrob]

While writing the following plantuml, docsify stopped rendering it:

@startuml
object "My-Object" as u #fffccc
package "my-package" as ds {
    map "abc" as ds_m  {
        Name => alpha
        nca => red
    }
        map "def" as ds_vsdi_i {
        Name => beta
        nca => green
    }
    map "xyz" as ds_nu {
        Name => gama
        nca => blue
    }
}

The issue basically started when I created the package "my-package". As this code works properly on the plantuml server, I suspect the issue is the docsify plugin that sends it corrupted to the plantuml server. Would be great to understand what's going wrong. Thanks
