The entity-class mapping is invalid

Question

I am having trouble in debugging mapping error of Entity. When I run php bin/console doctrine:schema:validate , It shows the error , which is as follow

[FAIL] The entity-class App\\Entity\\Company mapping is invalid: The association App\\Entity\\Company#policies refers to the owning side field App\\Entity\\Policy#company_id which does not exist.

I tried this post ( Entity class mapping is invalid ) which is pretty much same with me but seems like not working.

This is my Company Entity

<?php

Answer 1

company_id does not exist in the entity only in the table. So try mappedBy="company instead? Hope it helps!
