When executing vitest we receive the following error

TypeError: Cannot read properties of null (reading 'transformMode')

Sometimes the error doesn't show up and our tests are passing.
Here is our vitest.config.ts
import { fileURLToPath, URL } from "node:url"
import vue from "@vitejs/plugin-vue"
import vueJsx from "@vitejs/plugin-vue-jsx"
import VueMacros from "unplugin-vue-macros"
import { defineConfig } from "vitest/config"
export default defineConfig({
appType: "spa",
plugins: [VueMacros.vite({ plugins: { vue: vue(), vueJsx: vueJsx() } })],
resolve: {
alias: {
"@": fileURLToPath(new URL("./src", import.meta.url)),
"./runtimeConfig": "./runtimeConfig.browser",
},
},
envPrefix: "VUE_",
