Collections/pagination oddity in 1.0.0 #2161

brycewray · 2022-01-09T15:53:01Z

The bug:
Beginning in 1.0.0, templating which formerly allowed for paginated output of a collection is broken. (Error message output below.) I didn't see this bug when using any of the 1.x beta versions, nor with any other Eleventy version all the way back to 0.9.0 in 2019.

To reproduce:
Steps to reproduce the behavior:

Upgrade the site to Eleventy 1.0.0.
Run Eleventy (npx @11ty/eleventy in package.json).
The build attempt fails with an error message (below).

Expected behavior:
The site would build, with normal "posts" collections pagination (151 posts, paginated 5-per-page) on the /posts route, as it always did prior to version 1.0.0.

Error message:

Possible workaround: Explicitly set the permalink value for the pagination:

@pdehaan Thanks! Actually, project is good for now, so I can wait until this is resolved. Since it was fine prior to 1.0 (and others are having the issue), am assuming a fix will come.

zachleat · 2022-01-09T20:47:21Z

First thought was that it might be related to #1956 Did you test beta 10 or canary 50?

brycewray · 2022-01-09T20:49:42Z

First thought was that it might be related to #1956 Did you test beta 10 or canary 50?

No. I upgraded to 1.0.0 from 1.0.0-beta.2; and I never used any canary version.

zachleat · 2022-01-09T20:52:26Z

Can you test Beta 9 and see if it works? (and optionally Beta 10 to see if it doesn’t)

brycewray · 2022-01-09T20:59:13Z

Tried installing each without success (got the No matching version found for error), even though I matched the version names shown on the Tags page:

npm i -D @11ty/[email protected]

Is my syntax wrong?

pdehaan · 2022-01-09T21:21:37Z

Weird, I can do npm i @11ty/[email protected] (macOS Monterey 12.1).

@pdehaan Thanks. Tried it without -D as well (as per yours) and still no joy. Anyway, looks like you showed @zachleat what he needed to see.

Also, FWIW, I did npm view @11ty/eleventy and saw that beta is 1.0.0-beta.10, so tried npm i -D @11ty/eleventy@beta and, sure enough, it loaded that version (of course, still has the same bug, as in what @pdehaan showed above). No idea why the other requests for specific versions didn't work. 🤷‍♂️

pdehaan · 2022-01-10T02:00:49Z

And looks like I'm using the official npm registry at https://registry.npmjs.org/:

npm config ls -l | grep registry

metrics-registry = "https://registry.npmjs.org/"
; metrics-registry = null (overridden)
registry = "https://registry.npmjs.org/"

The output is too large to dump here, but you can get all the npm info (dist-tags, versions, times, .tgz info, etc) for @11ty/eleventy using npm info @11ty/eleventy --json.

brycewray · 2022-01-10T02:05:05Z

@pdehaan Yes, it's as if my npm i is pulling from a different place where not all the versions exist. Very weird stuff.

brycewray · 2022-01-10T14:10:31Z

@pdehaan Just FYI: this morning, out of curiosity, tried the following and was able to load both beta.9 and beta.10 successfully thereafter:

Turned on the Cloudflare 1.1.1.1 tool on the Mac, which automatically disabled the macOS Private Relay feature (and I did try turning that off yesterday but had no luck with the loads).
Did both loads.
Turned Cloudflare 1.1.1.1 back off and re-enabled Private Relay.
Repeated the loads successfully, settling on beta.9.

Once again — 🤷‍♂️. Have now reverted my repo to beta.9 for now and it works just fine, as your fork did. Guess I'll stick with that version until there's a resolution to this issue in stable 1.0.x.

Thanks again!

zachleat · 2022-04-15T15:14:00Z

I don’t think this is the same issue as #2167 BUT I do this the fix that went up for #2167 will likely fix this one too. Please retest after 2.0.0-canary.5 is shipped!

5t3ph · 2022-06-04T22:56:16Z

Hey @zachleat - here to report I think a related issue as of v2.0.0-canary.11. Here's my test repo: https://github.com/5t3ph/issue-11ty-collection-pagination

(Happy to move to a new issue if you think it's separate)

Does it seem to be a data cascade issue for the permalinks, perhaps?

zachleat · 2022-06-16T20:45:53Z

@5t3ph sorry for the late reply here—this was indeed a different issue! (EXCELLENT test case tho)

I tracked down the issue to #1173

---
pagination:
  data: collections.pages
  size: 1
  alias: blah
permalink: "/pagination/{{ blah.fileSlug }}/"
---
{{ blah.fileSlug | log }}

works as expected. Please upvote #1173!
