Quick Fix: In Next.js, avoid naming your client components ‘app’; It’s a reserved word in NextJS; this can cause conflict with the router path resulting in the ‘Unknown root exit status’ error. Rename the component to something else, such as ‘appComponent’.

The Problem:

In a NextJS application, attempting to access a function named audioChunks results in an error with the message "Unknown root exit status.". The audioChunks function is designed to retrieve chunks of audio data from a MongoDB database. Upon further investigation, it was discovered that the error message is linked to a specific line of code within the AudioList component: const theResult = await audioChunks(chanlID). Upon commenting out this line, the error disappears, suggesting that the issue lies within the audioChunks function itself.

The Solutions:

Solution 1: Identify Reserved Words

If you face the ""Unknown root exit status." error in a NextJS web app, it might be because you have named a client component app.tsx. NextJS seems to hold "App" as a reserved word, or its configuration might get confused between the app router path and the app client component.

  1. Revert Changes:
    Back out your changes until you can reproduce the error.

  2. Identify the Suspect:
    Look for a client component named app.tsx, such as in the case described by the solution provider.

  3. Rename the Component:
    Rename the app.tsx client component to something else, like appComponent.tsx.

  4. Confirm Resolution:
    Confirm that the error is resolved by running your app again.

  5. Further Investigation:
    If the error persists, continue debugging to identify the actual cause.

Remember to be mindful of reserved words or potential configuration issues when naming components or files in NextJS.

Q&A

Why am I receiving the error "Unknown root exit status" when using audioChunks() in my Next.JS application?

Ensure that you are not using "App" as a component name, as it may conflict with Next.JS internal components.

What does mongoose.connect() do in connectMDB()?

It establishes a connection to a MongoDB database using the provided URI.

What could cause the "Unknown root exit status" error in Next.JS?

Using "App" as a component name can cause this error due to potential conflicts with internal Next.JS components.
