ENAMETOOLONG on long slug

[sukhcha-in]

I'm facing this issue when slug is too long, any way to fix this other than trimming slug?
What is the maximum limit for slug in this case?

Happening in production only, works fine in dev environment.

Isn't this a Linux issue? I think in Linux file names can be up to 255 characters in size. What OS are you using locally?

[Crinchy]

Any update on this?

[icyJoseph]

Aha, this is a new take on this.

So someone requests route with these many characters, and that's causing it to error like this? Do the urls have .html extension? can you tell a bit more of the whole setup where this happens?

[Crinchy]

Heres a error log of this case:

I have a dynamic route [slug] with ISR enabled and now, when you just hit the website with a long url, the application throws an error because through the linux limit, next.js cant write the file.

[icyJoseph]

Does the app crash upon this? What does the end user see? The dreaded 500 Internal Error page?

[Crinchy]

The end user is receiving a 404 not found, but in the background, the application is logging this error.

I am seeing this but with a particular scenario, looks like someone is adding some kind of extra text, like this:

Failed to update prerender cache for /different-is-better-than-better/'Different is Better Than Better' .html']

I am not sure if this is some kind of attack of bot crawling, but if you look my url is definitely shorter than 256, the extra text is the problem.
