When I try to edit a page to upload 2 documents, I get an error.

Procedure: I edit the node, upload the first document. Then I insert a new field to upload the second document. However, the second field does not appear and I get the following error message in dblog:

"Twig\Error\LoaderError: Template "themes/bootstrap_sbv/layout/sbv-personenseite-layout.html.twig" is not defined. in Twig\Loader\ChainLoader->getCacheKey() (line 10 of webpath/docroot/modules/ds/templates/ds-entity-view.html.twig).

I have tried to include the layout in the "ds-entity-view.html.twig" file.

{% include "/themes/bootstrap_sbv/layouts/sbv-personenseite-layout.html.twig" %}

But it doesn't work.

Curiously, everything works on the local environment. Only on the test and production environment I get the error. I have a custom theme on my Drupalsite.

  • Can you ensure that your template is present in the right location for non-working environments? Commented Jan 23, 2020 at 10:43
  • Not sure if it makes any difference, but instead of using an absolute path {% include '/theme/my_theme/dummy...' %} you can use a module's or theme's machine name as namespace {% include '@my_theme/dummy...' %} - this way you are safe if your modules/themes are split in .../contrib/... (from drupal.org) and .../custom/... (own code) sub-folders Commented Jan 23, 2020 at 11:11
  • I tried to add {% include "@bootstrap_sbv/layouts/sbv-personenseite-layout.html.twig" %} but get the following error Twig\Error\LoaderError: Template "@bootstrap_sbv/layouts/sbv-detail-page-layout.html.twig" is not defined in "modules/ds/templates/ds-entity-view.html.twig" at line 1. in Twig\Loader\ChainLoader->getCacheKey() (line 142 of /webpath/docroot/vendor/twig/twig/src/Loader/ChainLoader.php).

  • @Zeroplexer after giving it a thought I notice that the error cames from DS module. It seems to me that is possible that you are using custom layouts and you have a typo on the template route for that layout. Check this drupal.stackexchange.com/questions/162482/… Commented Jan 23, 2020 at 14:20

    Note that all Twig templates should always reside inside the /templates subfolder of your theme/module. Commented Jan 23, 2020 at 14:53

I came across this error when I wanted to use a database state, which was created with Version 10.2.2 and my Drupal instance was on 10.1.2.

Updating fixed the issue.

Moving the templates to the Templates folder themes/THEMENAME/templates has solved the problem. I also had to change the path in the THEMENAME.layouts.yml

Pay attention to @my_theme syntax it refers to themes/my_theme/templates folder while the desired template is located into themes/my_theme/layouts folder.

So what I suggest is to use a relative path to include the template, something like that:

{% include '../../../themes/bootstrap_sbv/layouts/sbv-personenseite-layout.html.twig' %}

  • Unfortunately it didn't work I get this error: Twig\Error\LoaderError: Template "@bootstrap_sbv/layouts/sbv-detail-page-layout.html.twig" is not defined in "modules/ds/templates/ds-entity-view.html.twig" at line 1. in Twig\Loader\ChainLoader->getCacheKey() (line 142 of /webpath/docroot/vendor/twig/twig/src/Loader/ChainLoader.php).

    Great advice! By writing the absolute path, then swapping-in @my_theme for /themes/my_theme/templates, I got what I came here for. Commented Jun 23, 2021 at 9:50
