I’m working on a Symfony
3.4.6 app, that has a lot of YAML configuration files in the
[project root]/config/packages. I added a key to one of them (let’s say
xyz: ... foo: bar: 123 buz: 567
Now I’m getting an error:
In ArrayNode.php line 319: Unrecognized option "foo" under "xyz"
I took a look into the
ArrayNode.php#319. Well, the thing is clear: arbitrary / additional keys are not allowed. There seems to be something like a whitelist. But where is it defined / how to extend it (add the new keys to it)?
How to solve the "unrecognized option" issue by adding keys to Symfony configs?
