`, but how should I find the exact cause from the error log? It does not provide any useful details (see below screenshot)\r\n\r\n---\r\n\r\nAnother question, as I guess my error is because of this:\r\nShould I wrap `watch()` inside `onMounted()`? or in another word, can I do it? I didn't find any corresponding example in Vue documentation... \r\nSorry if this is a dumb question, as I'm a react guy :(\r\n```vue\r\n\u003Cscript setup lang=\"ts\">\r\nimport { useLocalStorage } from '@vueuse/core';\r\nimport { watch } from 'vue';\r\n\r\nconst nfcapiEnvRef = useLocalStorage('vp-nfcapi-env', 'staging', {\r\n deep: false,\r\n listenToStorageChanges: true,\r\n writeDefaults: true\r\n});\r\n\r\nwatch(nfcapiEnvRef, (value, oldValue) => {\r\n const htmlDataSet = document.documentElement.dataset;\r\n oldValue && (htmlDataSet.nfcapiEnv = oldValue.toLowerCase());\r\n htmlDataSet.nfcapiEnv = value.toLowerCase();\r\n}, { immediate: true });\r\n\u003C/script>\r\n```\r\n\r\n---\r\n\r\nScreenshot of the error:\r\n\r\n\r\n\r\n\r\n\r\n### Reproduction\r\n\r\nThis is not a bug, but a question\r\n\r\n### Expected behavior\r\n\r\nN/A\r\n\r\n### System Info\r\n\r\n```sh\r\nSystem:\r\n OS: Windows 10 10.0.19045\r\n CPU: (16) x64 11th Gen Intel(R) Core(TM) i9-11900K @ 3.50GHz\r\n Memory: 30.87 GB / 63.84 GB\r\n Binaries:\r\n Node: 18.16.0 - C:\\NodeJS\\node.EXE\r\n Yarn: 1.22.19 - C:\\NodeJS\\yarn.CMD\r\n npm: 9.8.0 - C:\\NodeJS\\npm.CMD\r\n pnpm: 8.6.7 - C:\\NodeJS\\pnpm.CMD\r\n Browsers:\r\n Edge: Spartan (44.19041.1266.0), Chromium (114.0.1823.82)\r\n Internet Explorer: 11.0.19041.1566\r\n npmPackages:\r\n vitepress: ^1.0.0-beta.5 => 1.0.0-beta.5\r\n```\r\n\r\n\r\n### Additional context\r\n\r\nN/A\r\n\r\n### Validations\r\n\r\n- [X] Check if you're on the [latest VitePress version](https://github.com/vuejs/vitepress/releases/latest).\r\n- [X] Follow our [Code of Conduct](https://vuejs.org/about/coc.html)\r\n- [X] Read the [docs](https://vitepress.dev).\r\n- [X] Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.",[2959],{"name":2960,"color":2961},"question","5D5FAE",2627,"How should I trace build error?","2023-07-24T00:04:51Z","https://github.com/vuejs/vitepress/issues/2627",0.75995135,["Reactive",2968],{},["Set"],["ShallowReactive",2971],{"$fTRc1wZytZ_XrK4EfJfei_Sz-An4H4Yy6syhVxH_PVJc":-1,"$fcbnE8qa1tdVm5nXnkBF0cwO7SrAGziVG4YgRLdXu_IA":-1},"/vuejs/vitepress/4096"]
