Sometimes adapter-cloudflare hangs after the site is built

[buhodev]

Describe the bug

Sometimes the cloudflare adapter is stuck after sveltekit built the site.

And it can take up to 30min if I'm not supervising:

But this is usually what the whole step takes:

And those 48sec is for the same built but retried much later.

And the logs of the successful build:

Additional Information

I'm prerendering about 620 pages (last time I checked) which are generated at build time with dynamic routes /docs/[provider]/[name]/[major]/[minor]/[...slug]. I'm using an entries function in [...slug] to calculate all the permutations.

I'm encountering the same issue. It looks similar to this issue which was reported in 2021: #965

I'm guessing this is due to the esbuild step that occurs at the end of the build.
