yaml ruby parsing Ruby

I'm experimenting with I recently switched to I'm having trouble parsing a nested YAML structure in Ruby using the `yaml` library, specifically dealing with key duplication when the same key appears at different levels of nesting... Here's the YAML I'm trying to parse: ```yaml configurations: - name: server settings: timeout: 30 retries: 5 - name: database settings: timeout: 15 retries: 3 options: timeout: 10 ``` When I attempt to parse this YAML into a Ruby hash using the following code: ```ruby require 'yaml' yaml_data = File.read('config.yaml') parsed_data = YAML.load(yaml_data) puts parsed_data.inspect ``` I find that the `timeout` key gets overwritten because it appears multiple times in different contexts. The output I receive is: ``` {"configurations"=>[{"name"=>"server", "settings"=>{"timeout"=>15, "retries"=>5}}, {"name"=>"database", "settings"=>{"retries"=>3, "options"=>{"timeout"=>10}}}]} ``` The `timeout` values are not stored correctly, and the one from the database settings seems to take precedence. I've tried using the `YAML.safe_load` method to handle the parsing, but that doesn't solve the key duplication scenario either. Is there a recommended way to handle this scenario, perhaps by customizing the parsing behavior or restructuring my YAML format? Any insights on best practices for managing similar situations would be greatly appreciated! I'm working on a service that needs to handle this. Any ideas what could be causing this? What's the best practice here? I'm working with Ruby in a Docker container on Windows 11. Could this be a known issue? I'm working with Ruby in a Docker container on Linux. This is happening in both development and production on Ubuntu 22.04. Thanks in advance! I'm on CentOS using the latest version of Ruby. Could someone point me to the right documentation?
