Underscore import alias breaks production build with "unref is not a function"

[HawkOnPK]

Hey,

i have a project where i often import {gettext as _}.
This works without issues in a develop mode (run dev).
But in a production run, started by node /getaiplan/webclientv2/.output/server/index.mjs the project fails, due to an error "unref(...) is not a function" an a 500 error code. After disabling components one by one, i found out that the alias import breaks the project execution. Importing with any other name (e.g. {gettext}, {gettext as _get\) did not cause this issue.

I would expect Vue to at least generate a more helpful error when these names are disallowed, or cause errors that have no stacktrace attached to find the problem source.

Vue: 3.5.13
I would have liked to open an issue instead for this, but was not able to produce a blitzstack scenario for this production build issue.

Could you provide the full code for a component that has this problem?

Currently I'm not able to reproduce the problem, but without a complete component I'm just guessing about what to include other than the _ alias.

I too have trouble recreating a small scenario showing the issue. It seems to not be docker/linux related. But i will have to see whether i get around experimenting in the company project itself to check when / how the issue arises.
Currently the most likely scenario i have, is that a vite bundle name might override the import name, maybe related to vitejs/vite#17608 . In this case it is not a vue issue itself.
