Twig LoaderError: Template is not defined

Question

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.

Answer 1

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

Answer 2

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' %}
