Show stack trace?

Is there any way to see a stack trace for API routes? Front-end errors do show a stack trace, though the line numbers seem to be wrong, but on the server it just shows a 500 error in the console and on-screen, with no stack trace or information at all. Is there any way to see what file, line, or any indication of what the actual error is?

Hi @Smef. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address your question about seeing stack traces for API routes and server-side errors in Nuxt, there are a few approaches you can consider: 1. Sourcemaps: Nuxt provides built-in support for sourcemaps, which can help with debugging by mapping compiled code back to the original source code. You can enable sourcemaps for both server and client builds in your Nuxt configuration:
export default defineNuxtConfig({
sourcemap: {
server: true,
client: true
}
})
export default defineNuxtConfig({
sourcemap: {
server: true,
client: true
}
})
This should help with more accurate line numbers in error traces Debugging (https://nuxt.com/docs/guide/going-further/debugging#sourcemaps). 2. Error Handling: Nuxt provides several ways to handle and display errors: - You can use the createError utility to throw errors with additional metadata, including stack traces:
throw createError({
statusCode: 500,
statusMessage: 'Internal Server Error',
stack: new Error().stack // This will include the stack trace
})

throw createError({
statusCode: 500,
statusMessage: 'Internal Server Error',
stack: new Error().stack // This will include the stack trace
})

- You can also customize the error page by creating an error.vue file in your project root. This allows you to display more detailed error information, including the stack trace if available Error Handling (https://nuxt.com/docs/getting-started/error-handling#error-page). 3. Debugging with IDE: For a more comprehensive debugging experience, you can set up debugging in your IDE. For example, JetBrains IDEs (like WebStorm or IntelliJ IDEA) offer debugging configurations that can help you step through your code and examine errors in detail Debugging with Node Inspector (https://nuxt.com/docs/guide/going-further/debugging#example-jetbrains-ides-debug-configuration). 4. Server-side Logging: For API routes and server-side errors, you might need to implement additional logging. You could use a Nuxt plugin to hook into error events and log them more verbosely:
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.hook('app:error', (error) => {
console.error('Detailed error:', error)
// You could log this to a file or external service
})
})
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.hook('app:error', (error) => {
console.error('Detailed error:', error)
// You could log this to a file or external service
})
})
This approach allows you to capture and log more detailed error information on the server side Error Handling (https://nuxt.com/docs/getting-started/error-handling#vue-errors). Remember that in production, you should be cautious about exposing detailed error information to clients for security reasons. It's often better to log detailed errors server-side and display a generic error message to users. If these approaches don't provide enough information, you might need to implement more detailed custom error handling and logging in your Nuxt application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Well, the AI thing was on the right track, though the suggestions were wrong It looks like there are no error message or stack traces on server routes by default, for whatever reason, but you can make a plugin to log or display them similar to the front-end routes
export default defineNitroPlugin((nuxtApp) => {
nuxtApp.hooks.hook("error", (error) => {
console.error(error);
});
});
export default defineNitroPlugin((nuxtApp) => {
nuxtApp.hooks.hook("error", (error) => {
console.error(error);
});
});
This does get you an error in the console like the front-end errors
