symfony 7 Unable to create the Doctrine Proxy directory "/tmp/cache/prod/doctrine/orm/Proxies".

[stloc]

Symfony 7.0.3
as soon as I deploy on the first call I get the error, on the second call it works! why ?

Interesting 🤔 I have no idea why it would fail, the /tmp directory is made for this, first time I see this.

Is this a new app, or following an upgrade? Can you share more details?

new Symfony app

        # If you want to include files and folders that are part of excluded folders,
        # add them at the end
        - 'var/cache/prod/**'

only second call OK :

even disabling this in doctrine.yaml (I have not database) :

when@prod:
    doctrine:
        orm:
            auto_generate_proxy_classes: false
            proxy_dir: '%kernel.build_dir%/doctrine/orm/Proxies'
            query_cache_driver:
                type: pool
                pool: doctrine.system_cache_pool
            result_cache_driver:
                type: pool
                pool: doctrine.result_cache_pool

it works if I delete var/cache/prod/doctrine before deploy

(otherwise I get the error when I first launch the lambda !)

[mnapoli]

Could it be a permission issue maybe?

[stloc]

maybe
