I have a little problem to realize my own block on the home page of the dashboard. I tried to follow this tutorial : https://sonata-project.org/bundles/block/master/doc/reference/your_first_block.html
But I have get the following error message:
An exception has been thrown during the rendering of a template ("The block service
sonata.block.service...
does not exist") in ...
Has someone else experienced this same issue, and/or knows how to fix this?
