To Reproduce

Sometimes, randomly, the build for the nextjs app that fumadocs is in completely fails with this error:

./content/carbon/index.mdx?collection=docs&hash=1d30f9ca6833ba4a9d23a2e59be4a0492e38327c0f064d1782befb73aa630964

}

This happens inconsistently, and rerunning the build works. I see it happen both in builds on GitHub actions and locally, and inconsistently so it's hard to track down. Figured I'd report it anyway

Current vs. Expected behavior

I expected it to built correctly like it usually does, but sometimes (like 1/10 times) it will fail

Did you reference any images in your document?

fuma-nama commented 2 months ago

We use image-size package to fetch image sizes, they have to be a valid image path/url. If you could provide a minimal production, I can help investigate the problem

thewilloftheshadow commented 2 months ago

Yes I do reference one image (external URL on our cdn: https://cdn.buape.com/CarbonWordmark.png) I'll try to get this to a reproduction repo tomorrow!

thewilloftheshadow commented 2 months ago

I haven't been able to reproduce this consistently isolated yet, but this is the file that it's erroring on (and the only image)

Carbon is a powerful framework designed for building HTTP Discord bots.

fuma-nama commented 2 months ago

Failed to reproduce, you're also on MacOS so I don't think it's OS-related. Perhaps it's because of other usages? ![alt](image) will be recognized as an image.

fuma-nama commented 2 months ago

I think it's likely two reasons:

the CDN was down/unavailable during the build
the CDN has unhandled problems/errors

The plugin only fetches the image size when needed so it shouldn't happen unless there's problem fetching the image. If the problem consists, please consider using Next.js Image component in MDX file directly.
