Augmented taxonomy entries site url error

[mikemartin]

Bug Description

When listing taxonomy entries, I'm hitting an absoluteURL() error when the augmented entries are being returned.
Call to a member function absoluteUrl() on null

I've narrowed the error down to the site_url config in the absoluteUrl function in vendor/statamic/cms/src/Routing/Routable.php on line 49. My temporary workaround is replacing $this->site()->absoluteUrl() with env('APP_URL', '/'). Error log gist is attached below.

vendor/statamic/cms/src/Routing/Routable.php:

public function absoluteUrl()
    {
        if ($this->isRedirect()) {
            return $this->redirectUrl();
        }

        return vsprintf('%s/%s', [
            rtrim($this->site()->absoluteUrl(), '/'),
            ltrim($this->uri(), '/'),
        ]);
    }

Content:

sections:
  -
    type: zones
    enabled: true
    zones:
      - the-storm-zone
      - the-rain-zone
      - the-cloud-zone

Fieldset:

title: Zones
fields:
  -
    handle: zones
    field:
      mode: default
      type: taxonomy
      localizable: false
      listable: hidden
      display: Zones
      taxonomy: zones
``

Template:

{{ zones }}
     {{ title }}
{{ /zones }}

Just encountered this as well. This is probably the same issue: #1852

@jackmcdade as this issue dates back to May, it'd be great if it could be given some attention for the next release. With Statamic being in such an advanced beta state I'm sure I'm not alone in having a near-live site that could benefit from being able to actually loop over a taxonomy - {{category}}{{slug}}{{/category}} is kind of a fundamental capability wouldn't you say?

We ran into the same isuue today. In my oppinion its related to incomplete refactoring of Site::get() usage sometimes with handle, sometimes with locale:

#2193

Perhaps my investigations of the issue could help fixing it.

Having a hard time reproducing this one, in both single site and multisite apps. Those of you with the issue, can you paste your config/sites.php config?

@jesseleite

<?php

return [
    'sites' => [

        'default' => [
            'name' => config('app.name'),
            'locale' => 'en_US',
            'url' => env('APP_URL', '/'),
        ]

    ]
];

            'locale' => 'en_US',

        ],

    ]

]

beta 36, php 7.3, installed into existing app.

faq_grouping:
 -
   category:  // taxonomy fieldtype
     - stuff

then

{{ faq_grouping }}
{{category}}{{slug}}{{/category}}
{{ /faq_grouping }}

'sites' => [

        'default' => [
            'name' => config('app.name'),
            'locale' => 'en_US',
            'url' => '/',
        ]

]

Should be fixed in next beta. Let us know if still an issue.

I looked up legend in the dictionary and it was just a picture of @jesseleite's beard.
