Possible Solution

I attached my composer.json so you could look at the packages that I have installed to see if they are what may be cauing this issue.

Additional Context

As far as we can tell no operational impact at this time, but we are concerned that it may have an impact in the future as we migrate to a newer version of Symfony.

Had tons of Failed to generate ConfigBuilder for extension
Found this phrase at ConfigBuilderCacheWarmer

After commenting out exception catching like this:

//            try {
                $this->dumpExtension($extension, $generator);
//            } catch (\Exception $e) {
//                if ($this->logger) {
//                    $this->logger->warning('Failed to generate ConfigBuilder for extension {extensionClass}.', ['exception' => $e, 'extensionClass' => \get_class($extension)]);
//                }
//            }

and running bin/console cache:warmup I’ve got true the reason:

In EnvVarProcessor.php line 172:
  Environment variable not found: "BLA_BLA_BLA".

So, to fix annoying Failed to generate ConfigBuilder for extension messages I had to just add accidentally missed BLA_BLA_BLA= to .env

I literally just logged in just to say thank you!

I had a very similar problem and was getting Failed to generate ConfigBuilder for extension errors when running certain bin/console commands. After spending several hours tracing through my code and Symfony code in an attempt to find the issue, I finally solved it by updating the bin/console file (I copied it from a recent fresh install of Symfony 5.4).

The site with this problem was originally created on Symfony 4 and had been updated to Symfony 5. While all the packages were updated, the actual bin/console file was still the original version. The old bin/console command handles the loading of .env variables differently than more recent versions and this was the cause of the error messages.

I was expecting the bin/console command to be automatically updated when the symfony/console package is updated, but apparently that is not how it works.

Same issue here. For me it was in an upgraded SF4 LTS to SF5 LTS project: Environment variable not found: "APP_SECRET".

Upgrading bin/console to use the new runtime component did not fix anything here, but still is a good idea.

Thanks to @igormukhingmailcom for the simple idea! The exception message should include the original exception message. See CacheWarmer/ConfigBuilderCacheWarmer.php around line 59.

Simply add $e->getMessage() to the log message to find the real reason:

$this->logger->warning('Failed to generate ConfigBuilder for extension {extensionClass}.' . $e->getMessage(), ['exception' => $e, 'extensionClass' => \get_class($extension)]);

I find it weird that I have to supply all environment variables upon build time to not get warnings. Env-vars are supposed to be runtime vars.

So if I have to set all env parameters to empty defaults, what’s the point of this warning? What is it warning me of? I still don’t get a warning if I forget to set the env var on the production server at runtime.

Hi, once I got this problem because in my services.yaml I had some parameters that wasnt on my .env files . Check that!

carlospauluk on Feb 15, 2023

Can we replace the log to $this->logger?->warning('Failed to generate ConfigBuilder for extension {extensionClass}.', ['exception' => $e->getMessage(), 'extensionClass' => \get_class($extension)]);

Currently the exception message is not visible

Tofandel on Nov 11, 2022

The Failed to generate ConfigBuilder for extension log warning includes the exception in the context, so you should have access to the exception message in your logs though.

HI, I have the same problem and i can’t use php bin/console make:migration or symfony console make:migration i have an error who said Command “make:migration” is not defined.
