CASL is not working properly in Vue Production Mode - vue.js

Question

I have defined some rules for specific roles, they all are working fine. But when I build vue project in production mode, all the rules gives false. Details are here below:
I have this file ability.js, which is giving me rules:
export const getRules = (role, userId) => {
const { can, cannot, rules } = AbilityBuilder.extract()
switch(role) {
case 'TENANT_ADMIN':
can('manage', 'all')
break
case 'TENANT_AGENT':
can('view', 'ConversationView')
break
case 'TENANT_AGENT_LIMITED':
can('view', 'ConversationView', { userId: userId })
break
}
return rules
}
I'm updating rules like this in App.vue (all values are valid)
this.$ability.update(getRules(role, userId))
I'm checking permissions using below code.
class ConversationView {
constructor(props) {
Object.assign(this, props)
}
}
this.$can('view', new ConversationView({ userId: Id }))
Now, when I run this code in local/development mode. It is working fine (giving me true where it needs to), but when I generate a production build it is not working as expected (always gives me false)
Development Build Command:
vue-cli-service build --mode local --modern
Development Build .env.local
VUE_APP_STAGE=development
NODE_ENV=development
Production Build Command:
vue-cli-service build --mode prod --modern
Production Build .env.prod
VUE_APP_STAGE=production
NODE_ENV=production
Let me know why this is happening.
Replicated the steps here.
Follow below link to view running and expected version:

Output:
Checking for '1' => true
Checking for 1 => false
Checking for '2' => false
Clone the same project in your local, or download it from [github 2
After running, we're getting this output:
Checking for '1' => false
Checking for 1 => false
Checking for '2' => false

Got the solution. Because of minification for production build code was not working as expected. Had to define modelName function to return proper name.
