./bin/magento config:show returns "Configuration for path: '...' doesn't exist" if config value equals to 0 or empty string

[OleksiiBulba]

Preconditions (*)

1. Magento 2.4-develop
2. Create module Vendor_Module
3. Create etc/config.xml in created module Vendor_Module with new config path default/vendor_module/general/value with value 0 or '' (empty string)

Steps to reproduce (*)

1. Open magento cli and run command ./bin/magento config:show vendor_module/general/value

Expected result (*)

1. Should return 0 or '' (empty string)

Actual result (*)

1. Command returns Configuration for path: "vendor_module/general/value" doesn't exist

I think it happens because there <magento_root>/vendor/magento/module-config/Console/Command/ConfigShowCommand.php:153 magento checks if value is empty and if it actualy is the error message is shown. But empty value does not mean that path does not exist. So we should check if path exist in different method.

@OleksiiBulba
Its correct that it renders Configuration for path: "vendor_module/general/value" doesn't exist
But what should it render on empty value? Maybe an empty value error?

Hi @milindsingh
It is confusing when you try to get value from path but you got "path does not exist". I think at least the message should not say "does not exist" because it does exist but has empty value
