Handlebars url filter stopped working

[marcinwrochna]

Compiling a handlebars file using the url filter, like say input/index.md with

<a href="{{ url '/upload/foo.pdf' }}">foo</a>

fails with an error:

[11ty] 1. Having trouble rendering hbs template ./input/index.md (via TemplateContentRenderError)
[11ty] 2. pathPrefix (String) is required in the `url` filter. (via Error)

This happens both when the path prefix is set through the command line with --pathprefix="/bar/" or through config (return {..., pathPrefix: "/bar/"}).

Stack trace

[11ty] Original error stack trace: Error: pathPrefix (String) is required in the `url` filter.

[11ty] Using pathPrefix: /bar/

Indeed, adding console.log(pathPrefix) in the function in Url.js shows that the function argument "pathPrefix" is actually:

{
  lookupProperty: [Function: lookupProperty],
  name: 'url',
  hash: {},
  data: {
    root: {
      eleventy: [Object],
      pkg: [Object],
      page: [Object],
      collections: [Object]
    }
  },
  loc: { start: { line: 1, column: 9 }, end: { line: 1, column: 44 } }
}

Environment: Tested on a fresh new install: Eleventy 1.0.2 (Linux, npm 8.19.1), [email protected]. It worked OK with Eleventy 0.12.1, same handlebars version. Works fine with liquid templating.
