error:
▶ src/pages/components/Header/MenuButton.astro
undefined
error Cannot read properties of null (reading 'default')
it's weird because that file isn't referenced anywhere. I tried debugging for an hour or so before I decided to unreference because this error always seems to pop up and everything works just fine in dev.
It really really hates this file for some reason that I don't know. The only way to build my project is to actually delete this file completely even if i never reference it anywhere. 
#run build fails, run dev works just fine

Hi @late shard. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Hmm, I don't know enough to give you a confident answer yet. However, the error you mentioned might be related to an issue with importing or rendering an invalid component. You can try looking for errors in the component you are importing and rendering, and make sure it's working correctly. Consider opening an Astro starter template from astro.new (https://astro.new) and troubleshooting just your component in a minimal Astro project source (https://docs.astro.build/en/guides/troubleshooting#expected-a-default-export).
If you still face issues, you can check the Astro documentation (https://docs.astro.build) for more information or consider opening an issue on the Astro GitHub repository (https://github.com/withastro/astro/issues).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
@late shard kapa.ai is still learning and improving, please let us how it did by reacting below
@lyric wagon here is the component in question MenuButton.astro :
const { url } = Astro.props;
<a
class="btn m-1"
href={url}
<slot />
</a>
and this is how data is passed to it in another file :
<MenuButton url="#">Home</MenuButton>
Let me check the knowledge base for you. One moment! :books:
Based on the provided code, your MenuButton.astro component seems to be correctly set up to receive the url prop. The usage of the component in another file also appears to be correct. If you're still facing issues, you can try the following steps:
- Ensure that you have imported the
MenuButtoncomponent in the file where you're using it. The import statement should look like this:
import MenuButton from './components/Header/MenuButton.astro';
Make sure the import path is correct and points to the MenuButton.astro file.
- If the issue persists, consider creating a minimal Astro project using an Astro starter template (https://astro.new) and test your
MenuButtoncomponent in that environment. This can help you identify if the issue is related to your specific project setup or the component itself.
