@ljq29 你好！我是Dosu，一个可以帮助解决bug、回答问题并成为贡献者的机器人。在等待人类维护者的过程中，我会尽力帮助你。

The issue of the URL being empty could be due to several reasons:

1. Environment Variables: If the URL is supposed to be generated from environment variables like CONSOLE_API_URL, CONSOLE_WEB_URL, etc., ensure these are set correctly. If they are left empty, they default to the application's domain, which might not be what you expect ^[1].

2. File Upload Process: Ensure that the file upload process is correctly configured. The file should be uploaded and processed properly to generate a valid URL. Check the configuration in the "Start Node" and ensure that the file variables are correctly set up ^[2].

3. Code Logic: Verify the logic in the code node where the URL is being generated. Ensure that the URL is being constructed correctly and that all necessary parameters are being passed to the function.

Review these areas to identify where the URL might not be getting set correctly.
