Symfony: property does not exist - 500 Internal Server Error - ReflectionException

Question

I deleted $hearAboutIndustry from the object and now I get the error below only on the production server, and not on the local and intermediate server! Any idea why or solution?

 Property Tete\AdminBundle\Entity\Customer::$hearAboutIndustry does not exist 500 Internal Server Error - ReflectionException 

config_prod.yml

 doctrine: orm: metadata_cache_driver: apc result_cache_driver: apc query_cache_driver: apc 

What am I doing to solve it so far:

• Removed recipients and setters from the object.
• Deleted entire folders of caches and logs and re-created back, including 777.
• Just in case, run cache:clear --env=prod
• Search hearAboutIndustry in all project directories / files. No reference.
• Run doctrine:schema:update . DB is updated.
• Run doctrine:generate:entities . Object updated.
• Application / Console Doctrine: cache: clear-metadata li>
• app / console doctrine: cache: clear-query
• app / console doctrine: cache: clear-result

Answer 1

As Adam said in a comment, it is better to restart apache if all of the above solutions have been tried and failed. Decision:

sudo apachectl graceful

Answer 2

• php app / console doctrine: cache: clear-query --env = prod

Delete all query cache entries

• php app / console doctrine: cache: clear-result --env = prod

Delete all result cache entries

• php app / console doctrine: cache: clear-metadata --env = prod

Delete all metadata cache entries

• php app / console cache: clear --env = prod

Flushing cache for prod environment using debug false

And don't forget to put --env = prod in your commands

"Old, but it still happens" If none of the solutions mentioned above works, try deleting the object cache file manually: (for example, the path of the Entity entity file must be like this)

projectdirectory \ projectname \ var \ cache {dev or prod} \ jms_serializer \ Tete-AdminBundle-Entity-Customer.cache.php

Answer 4

I had a similar problem, I just used the doctrine: mapping: import and that’s it.

We had the same problem, and in our case (Nginx) restarting Nginx did not help.

But restarting memcache was the right solution:

 sudo service memcached restart
