Could not resolve "esm-env"

[myftija]

Hi,
I am getting an error in the build about Vite not being able to resolve esm-env, which is used by sveltekit-flash-message.

Here is the error message:

✘ [ERROR] Could not resolve "esm-env"
    ../../node_modules/.store/sveltekit-flash-message-virtual-b0a0b5868a/node_modules/sveltekit-flash-message/dist/client.js:3:35:
      3 │ import { BROWSER as browser } from 'esm-env';
        ╵                                    ~~~~~~~~~
You can mark the path "esm-env" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.

Vite version: 5.4.0
sveltekit-flash-message version: 2.4.4
SvelteKit version: 2.5.10

I wasn't able to find a workaround. Any clues what could be the issue?
