404 Error from Azure API from version 7.3.0

[ymtdzzz]

Describe the bug
From the version 7.3.0, Faraday::ResourceNotFound: the server responded with status 404 occurs when calling #embeddings method to send a request to Azure.

To Reproduce
Steps to reproduce the behavior:

1. Configure to use Azure OpenAI

OpenAI.configure do |config|
  config.access_token = ENV.fetch("AZURE_OPENAI_API_ACCESS_TOKEN", "")
  config.uri_base = ENV.fetch("AZURE_OPENAI_API_URI_BASE", "")
  config.api_type = :azure
  config.api_version = ENV.fetch("AZURE_OPENAI_API_VERSION", "")
  config.request_timeout = 60
end

2. Call #embeddings

> client = OpenAI::Client.new
> client.embeddings(parameters: {model: "text-embedding-3-small", input: "test-input"})

3. See error

Faraday::ResourceNotFound: the server responded with status 404
from /Users/your-name/.asdf/installs/ruby/3.2.5/lib/ruby/gems/3.2.0/gems/faraday-1.10.4/lib/faraday/response/raise_error.rb:22:in `on_complete'

I have confirmed that it works on the version 7.2.0

Expected behavior
No errors occurred

Possible solution
Maybe the following change might be the cause:

#527

ruby-openai/lib/openai/http.rb

Lines 21 to 26 in a5714d3

	def json_post(path:, parameters:, query_parameters: {})
	conn.post(uri(path: path)) do |req|
	configure_json_post_request(req, parameters)
	req.params = query_parameters
	end&.body
	end

ruby-openai/lib/openai/http.rb

Lines 88 to 91 in a5714d3

	def uri(path:)
	if azure?
	base = File.join(@uri_base, path)
	"#{base}?api-version=#{@api_version}"

If we use Azure, req.params already has the api_key param. So should we merge query_params instead of overwriting ?

Hi @ymtdzzz, thank you for the clearly specified issue and apologies for any inconvenience. Would you be able to test if #532 does indeed fix the issue? Thank you.

@alexrudall , thanks for your rapid response!
#532 seems to fix this issue 👍

[3] pry(main)> OpenAI::VERSION
=> "7.3.1"
[4] pry(main)> response = client.embeddings(parameters: {model: "text-embedding-3-small", input: "test-input"})
[5] pry(main)> response.dig("data", 0, "embedding").length
=> 1536

Thank you @ymtdzzz, v7.3.1 is now released and contains the fix.
