[Bug] Creating a static website fails when primaryDomain is empty

[Dearanlan]

Environment

• 1Panel version: v2.2.5
• Release channel: stable
• OS: Debian GNU/Linux 13 x86
• Docker: 29.7.2

Description

Creating a static website from the 1Panel Websites page fails.

The request contains an empty primaryDomain and empty siteDir, while the
domains array contains the actual domain.

Steps to reproduce

1. Open 1Panel Websites.
2. Create a static website.
3. Set the domain to tesat.cn.
4. Submit the form.

The frontend sends a request to POST /api/v2/websites with this sanitized
payload:

{
  "primaryDomain": "",
  "type": "static",
  "alias": "qwer",
  "domains": [
    {
      "domain": "tesat.cn",
      "host": "tesat.cn",
      "port": 80,
      "ssl": false
    }
  ],
  "siteDir": "",
  "enableSSL": false
}

Expected behavior

The static website should be created successfully, or the UI should show a
clear validation message identifying the missing required field.

Actual behavior

Website creation fails.

HTTP response status and response body were not captured from the frontend
request.

Additional information

Session cookies and CSRF tokens are intentionally omitted.

Update

The API returns the following error when creating a static website:

服务错误: json: cannot unmarshal object into Go value of type []request.WafWebsite

Environment:

• 1Panel v2.2.5 stable
• Debian 13 x86
• Docker 29.7.2

This suggests that the frontend sends a WAF website configuration as a JSON object, while the backend expects an array of request.WafWebsite.
