The build fails while deploying on Netlify with the latest 6.0.0 version of adapter-netlify

[orangecoloured]

I have this error while the build stage on Netlify.

'/experiments/:1' is not a valid path according to the URLPattern specification

I have this route experiments/[slug]/+page.svelte, experiments/[slug]/+page.server.ts. It works fine with the pre-6 netlify-adapter package. Do I need to change anything in the config in my +page.server.ts or somewhere else? Or is it a netlify-adapter bug?

cc: @serhalp in case I don’t figure this out first

I suspect

kit/packages/adapter-netlify/index.js

Line 248 in 8c2384a

parts.push(`:${parts.length}`);

is incompatible with the new Netlify functions API. The dynamic segment has to start with a letter rather than a number

[serhalp]

oh, damn, yes, just add a prefix here. I was just working on a PR this weekend that adds a bunch of integration test coverage to the adapter and encountered this exact issue 🤦🏼.

I drafted a quick fix at #15332

You can upgrade to 6.0.2 and this should be fixed

@teemingc here's the working deployed example

Here's how it looks:

Thank you this was helpful. I'm really sorry about this. I let a regression through in https://github.com/sveltejs/kit/pull/15203/changes#diff-cc76725f3c6f8ff40fb8605aff3b0d3eeefc561e4a6c9a162b79dda99c95dedaL322 where we moved to the newer Netlify routing system without matching load function data paths /__data.json, etc.. I should be able to get a fix up soon and a test so that this doesn't happen again.

Created #15367

Ok the fix has been released in version 6.0.3 https://github.com/sveltejs/kit/releases/tag/%40sveltejs%2Fadapter-netlify%406.0.3

@teemingc All good. Everything works fine. 👌
