This is not a duplicate of e.g. Referencing a template in Twig / Symfony2 because creating bundles as applications is deprecated/not recommended anymore and therefore the answer is not applicable anymore. How do I reference my own template in a Sylius grid?
What I tried:
1.
options:
template: "@App/Order/Grid/Field/channel.html.twig"2.
options:
template: ":Order/Grid/Field:channel.html.twig"3.
options:
template: "templates/Order/Grid/Field/channel.html.twig"4.
options:
template: "Order/Grid/Field/channel.html.twig"(I tried some of these on the basis of the documentation: https://docs.sylius.com/en/1.6/components_and_bundles/bundles/SyliusGridBundle/field_types.html#twig-twig , https://docs.sylius.com/en/1.6/components_and_bundles/bundles/SyliusGridBundle/your_first_grid.html)
In all cases it says the template was not found. Any ideas?
