Symfony 5.3 The parameter "21" must be defined - php

Question

i developed a symfony project.
Everything words fine on dev machines (using symfony server on port 8000).
When i clone the git in my production server i got this error:
Executing script cache:clear [KO] [KO] Script cache:clear returned
with error code 1 !! !! // Clearing the cache for the prod
environment with debug !! // false !! !! !! In
App_KernelProdContainer.php line 674: !! !! The parameter "21" must
be defined. !! !! !! cache:clear [--no-warmup]
[--no-optional-warmers] !! !! Script #auto-scripts was called via
post-update-cmd
I tried to:
delete the var/cache/* content
execute a php bin/console cache:pool:clear cache.global_clearer
set the env to prod and to dev
Nothing changes.
I have an ubuntu 20 with php-fpm7.4, mysql 8.0.
The error log shows:
AH01071: Got error 'PHP message: PHP Fatal error: Uncaught
Symfony\Component\DependencyInjection\Exception\InvalidArgumentException:

I executed composer dump-env .env and he generated .env.local.php, with
return array (
'APP_ENV' => 'prod',
'APP_SECRET' => 'c6e083dd648f30951fb991cee1df42f9',
'DATABASE_URL' => 'mysql://[DBUSER]:'.urlencode('[dbpasswd]').'#127.0.0.1:3306/[dbname]?serverVersion=8.0',
);
What shall i do?
Thanks a lot.

Having the same error. The problem is comming from special characters in your password.
Indeed in .env variables you need to url encode. For example != become %21%2F but it cause error
The parameter “21” must be defined
Solution in config/packages/doctrine.yaml replace
url: '%env(resolve:DATABASE_URL)%'
by
url: '%env(DATABASE_URL)%'
