Config behavior changed since v1.3.6?

[PeterDaveHello]

I only get this error since v1.3.6, v1.3.5 works fine with the same configuration from the environment variable:

azure-openai     | 2024/05/12 06:35:30 Init from config file
azure-openai     | 2024/05/12 06:35:30 executable path: /app/azure-openai-proxy
azure-openai     | 2024/05/12 06:35:30 read config file error: open /app/config.yaml: no such file or directory

Checking https://github.com/stulzq/azure-openai-proxy/releases/tag/v1.3.6, maybe this is related?

My docker-compose.yml:

  azure-openai:
    image: stulzq/azure-openai-proxy:v1.3.5
    ports:
      - 8080:8080
    environment:
      AZURE_OPENAI_ENDPOINT: https://<aoai-deployment>.openai.azure.com/

After tracing the code, it seems AZURE_OPENAI_MODEL_MAPPER can't be empty, but the behavior doesn't change here, just the error handling in new versions:

	err := azure.Init()
	if err != nil {
		panic(err)
	}

As AZURE_OPENAI_MODEL_MAPPER doesn't seem to be required, maybe we can change the logic of this line?

if endpoint != "" && openaiModelMapper != "" {
