CRA to Vite migration, process is not defined error in 'mime-types' package.

[dethrtrns]

Hi there, I'm trying to migrate the project of my company where I work, from cra to Vite. Here's where I'm stuck:

I've checked out similar issues(all those issues have been marked as closed without any resolution) with other packages and all I got was a workaround of:
vitejs/vite#1973 (comment)
define: { 'process.env': {}, // to workaround the process.env error but not a permanent fix },
but it doesn't work in the production build, now it gives an error as the process is undefined!
I didn't face any such issues with other packages I'm using in the project.

Any help would be highly appreciated.
