调用setContent时Puppeteer意外关闭页面的调试求助

调用page.setContent时遇到Puppeteer自动关闭页面的问题，即使仅打开页面后等待，也会触发page.close()调用，最终抛出TargetCloseError。以下是相关代码、日志及初步排查信息，请求协助定位原因：

相关代码 #

chrome = await puppeteer.launch();
page = await chrome.newPage();
await page.setUserAgent(ua);
await page.setViewport({width: Number(width), height: Number(height)});
console.warn("here4");
if (input) {
    console.warn("input found");
    await page.setContent(input);
}
console.warn("here5");

运行日志 #

初步排查信息 #

• 日志中“Trying to kill”来自Process类的kill()方法，是对目标关闭的响应；
• 协议追踪显示page.setViewport后自动发送了Target.closeTarget指令，但代码中未主动调用；
• 即使仅打开页面后等待，也会触发page.close()调用。
