Symfony4 Mapping issue

Question

I got an error like:

Undefined index: id

I know there are few questions like that already present on a Stack Overflow, but the solutions didn't work for me. Could you please review my entities in order of figuring out what exactly is causing this issue?

SOLVED!

The issue was caused by redefined QuoteStrategy::getColumnAlias() method because "`" was added to query.

Have you checked your database schema? Are you sure it matches these entities? — ehymel

The schema was updated regularly according the latest Entities state using doctrine:schema:update --force --complete command — Roman Newaza
– Roman Newaza, Commented Aug 15, 2018 at 12:07
I would still check it within the db itself (I.e., not from symfony or doctrine), just to rule out all possible sources of the error. — ehymel

Off topic but it is a little bit strange that your id's are integers but you are passing them as strings. Used to seeing ORM\Id instead of ORM\Id(). Probably not the issue. — Cerad
– Cerad, Commented Aug 15, 2018 at 12:22
@ORM\Id() is generated by make:entity and id parameter is of string type which is normal — Roman Newaza
