Describe the bug
permalinkthat doesn't have a string-literal value. Error:the "path" argument must be of type string. Received type boolean (false)Sample codeeleventy.serverless.pathisn't in scope at any point at which you can set front matter via an asynchronous function. This means that if your template's parent layout has, say,<head><title>{{ title }}</title></head>in it, you can't set a page-wide value for the variabletitlethat involves querying it by passingeleventy.serverless.path.your_slugto a headless CMS and fetching the page data. Setting{% assign title = ... %}down in the template body doesn't help, as that isn't seen by the parent layout's{{ title }}. Error:ReferenceError: eleventy is not defined. Sample code..11ty.jstemplate doesn't help, either, because asynchronous filters don't seem to actually get called properly: Liquid sample code, Nunjucks sample codeTo Reproduce
-BROKENoff the end of a template fileExpected behavior
I expect to be able to populate the page-data / front-matter of pages I'm generating with 11ty serverless from fresh API calls against my headless CMS. Sadly, I can't.
Environment:
Additional context
The goal is to save on build time by first-view-time rendering each of the "event detail" pages of a calendar with thousands of events in its history. All data for the site is stored in Sanity.io.
It needs to be easy to get data into the title tags, OG cards, etc. of each page. Such HTML is generated by shared site-wide layouts, so simply assigning a value in the "inner body" of the template as seen at Algolia's recent blog post does not suffice.
I also had no luck trying the YAML-front-matter-based approach seen at 44:35 of Ben & Zach's June video. Although they seem to manage to get it to reference
eleventy.serverless.pathfrom front matter, Nunjucks & Liquid don't seem to be able to passeleventy.serverless.path.my_slug_keyto an asynchronous function (contacting my headless CMS) cleanly. See Liquid sample code, Nunjucks sample code. Also, even if I could get that to work, it'd break everything else I'm doing in my site, which is built with Liquid because I need its parameterized includes syntax, and doing a handoff from a Nunjucks parent to a Liquid child (with liquid parent templates) doesn't seem to work too well.The text was updated successfully, but these errors were encountered:
