WARN: b64_json rejected (status 400); retrying with response_format=url.
ERROR: image-gen status=400 request rejected: 远程服务器返回错误: (400) 错误的请求。

Verification failed for image-gen; settings NOT saved. Use -Force to save anyway.

使用的是agnes，已经确认设置命令没错
scripts\setup.ps1 -SetGen -BaseUrl https://apihub.agnes-ai.com/v1/images/generations -Key sk-xxx -Model agnes-image-2.1-flash -Verify

需要修改两个地方

修改位置 1：

原代码：

powershell
$body = @{ model = $resolvedModel; prompt = $Prompt; n = $N; size = $Size; response_format = 'b64_json' } | ConvertTo-Json -Depth 5
修改为：

powershell
$body = @{ model = $resolvedModel; prompt = $Prompt; n = $N; size = $Size; extra_body = @{ response_format = 'b64_json' } } | ConvertTo-Json -Depth 5
修改位置 2：
原代码：

powershell
$bodyUrl = @{ model = $resolvedModel; prompt = $Prompt; n = $N; size = $Size; response_format = 'url' } | ConvertTo-Json -Depth 5
修改为：

powershell
$bodyUrl = @{ model = $resolvedModel; prompt = $Prompt; n = $N; size = $Size; extra_body = @{ response_format = 'url' } } | ConvertTo-Json -Depth 5
