I have a view that comes from a .yml file. It is supposed to show an index I created manually. However, when I import the yaml file manually, the search is not triggered (i.e. when I enable Solr Search Devel, it does not yield any information regarding any search, and the server doesn't receive any request).

The strange thing is that if I manually create (through the GUI) the exact same view, the search is properly triggered, and Solr Search Devel shows informations on the search.

Why is my view not calling the Search API ? Could it be linked to something else than the yaml file itself ?

Here is my yml

For anyone experiencing the same issue, I managed to fix the problem.

In my case it was because one of the facets attached to the view referenced an unexisting field of my Solr index. Since /var/log/apache2/error.log was completely silent about this, I stumbled upon it completely randomly.

Check if all the facets you use reference existing fields.
