Hello, I have came across this sudden error, which has appeared out of nowhere. Tried going back in code and the problem seems to be in me using the USelectMenu component . Any help is welcomed 😄

Hi @Michal Winter. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some insights about the USelectMenu component and potential syntax issues in Nuxt. However, the specific error you're encountering ("SyntaxError: Unexpected token ';'") is not directly addressed in the given documents. The USelectMenu component is part of the Nuxt UI library and is used for creating advanced select menus with features like searching and multiple selection. It's possible that there might be a syntax error in how you're using this component. Here are a few things you can check: 1. Make sure you're using the correct syntax for the USelectMenu component. The basic usage should look something like this:

<template>
  <USelectMenu v-model="selected" :options="options" />
</template>

<script setup>
const options = ['Option 1', 'Option 2', 'Option 3']
const selected = ref(null)
</script>

<template>
  <USelectMenu v-model="selected" :options="options" />
</template>

<script setup>
const options = ['Option 1', 'Option 2', 'Option 3']
const selected = ref(null)
</script>

2. Check if you have any unnecessary semicolons (;) in your template or script section where you're using the USelectMenu component. 3. Ensure that all your props and attributes are correctly formatted. For example, make sure you're using the correct prop names as shown in the SelectMenu documentation (https://ui.nuxt.com/components/select-menu). 4. If you're using any custom slots or options, make sure they are properly formatted and don't contain any syntax errors. 5. Verify that you have imported and registered the USelectMenu component correctly in your Nuxt configuration. If you're still encountering issues, it would be helpful to see the specific code where you're using the USelectMenu component. The error message suggests a syntax problem, which could be in the component usage or in the surrounding code. For more detailed information about the USelectMenu component and its usage, you can refer to the Nuxt UI SelectMenu documentation (https://ui.nuxt.com/components/select-menu). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Well, when I save the code again, the error dissapears and the select menu is working fine. But then when I save again, the error pops up again.

Let me check the knowledge base for you again. One moment! :books: ---------------------- This behavior you're describing, where the error appears and disappears upon saving, suggests that there might be an issue with the development server or the hot module replacement (HMR) in your Nuxt project. While the knowledge sources don't directly address this specific scenario, I can provide some insights based on related information. 1. Development Server Issues: This could be related to how the Nuxt development server is handling file changes and recompilation. The Nuxt documentation on reporting bugs (https://nuxt.com/docs/community/reporting-bugs) mentions that some errors might not be properly reported to the user, which could explain the inconsistent behavior you're experiencing. 2. Potential Workaround: As suggested in a GitHub issue comment, you might want to try running the .nuxt/dev/index.mjs file directly to see if it provides a more detailed error message. This approach helped a user identify an issue with pdfmake:

   node src/.nuxt/dev/index.mjs

   node src/.nuxt/dev/index.mjs

This might give you a clearer error message that could help pinpoint the problem. 3. Check for Invalid JS Syntax: Another GitHub issue mentions a "Pre-transform error: Failed to parse source for import analysis because the content contains invalid JS syntax" GitHub Issue #29733 (https://github.com/nuxt/nuxt/issues/29733). Although this issue was resolved without a clear explanation, it's worth checking your code for any syntax errors that might be causing intermittent issues. 4. Nuxt and Nitro Versions: Ensure that you're using compatible versions of Nuxt and Nitro. Some users have reported that upgrading or downgrading these versions has resolved similar issues. 5. Import Statements: As mentioned in a GitHub comment, some users have resolved similar issues by replacing CommonJS require statements with ESM imports. If you have any require statements in your code, try converting them to import statements. 6. type: module in package.json: If you have "type": "module" in your package.json, try removing it temporarily to see if it resolves the issue. However, this is not a long-term solution if your project requires ES modules. If the problem persists, you might want to consider: - Clearing your Nuxt cache and node_modules, then reinstalling dependencies. - Checking for any Nuxt modules that might be causing conflicts. - Creating a minimal reproduction of the issue to share with the Nuxt community for more specific help. Remember, intermittent errors can be challenging to diagnose. If you can't resolve the issue, consider reporting it as a bug (https://nuxt.com/docs/community/reporting-bugs) to the Nuxt team, providing as much detail as possible about your setup and the steps to reproduce the problem. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Yep found that a while ago, thanks Looks like the temporary fix is a Nuxt version downgrade

brunomgmateus•5w ago

Thanks, just got bitten by this when using NuxtUi and the latest Nuxt, and was getting crazy thinking what I've done wrong.

Michal WinterOP•5w ago

Ye was exactly same for me.

manniL•5w ago

better - vite version downgrade

brunomgmateus•5w ago

Yup, I've overriden Vite version on package.json, and works so far.

Michal WinterOP•5w ago

So I should just add Vite to the dependencies list with the older version? Since I have not seen it in there 😄

brunomgmateus•5w ago

Just add something like:

"overrides": {
    "vite": "5.4.11"
  }

"overrides": {
    "vite": "5.4.11"
  }

to your package.json. This will force using vite 5 instead of vite 6. (from what I've understood from skimming through the issue, looks like its a NuxtUi bug on transitions of certain components, and currently affecting Vite 6). The override should just be a temporary fix, while the bug is solved upstream.
