unable to understand what this build issue is

[tejas-1206]

I am currently learning and integrating microfrontend architecture using mod-fed. My remote is a next 14 (react 18) app. My host is an react 18 app. It works absolutely great during dev phase (via vite dev). But when I run the build (vite build) and serve it (vite preview), it throws this error, as shown in the below screenshot.

Both remote and host use the same version of mod-fed and both share react,react-dom and axios libs.

Inspecting the build code, factory (as pointed in the screenshot by red squigly lines) is a boolean and invoking it causing the error. But I'm not sure why though. I would like to inspect further but I'm not sure where or which rabbit hole should I dive into.

I'm happy to share any additional information (as long as it doesn't involve sharing business logic) and I would love to understand why this issue exists only on deployed app and not during development.

Anything related to vite should go to module-federation/vite repo - core team does not maintain this integration

@ScriptedAlchemy But there is no discussions tab in module-federation/vite repo. So, asked here.
Can I raise this as an issue then, in that repo ?

Probably. Just use what's available. Issues works. Core team doesn't work on that codebase so we are not much help. It's community maintained just under our namespace
