当前浏览器适配器不支持文件注入

Error message

当前浏览器适配器不支持文件注入

What it means

The draft flow injects the video file directly into the page's <input type=file> via page.setFileInput. If the current browser adapter does not implement setFileInput, a CommandExecutionError is thrown telling the user to switch to Browser Bridge or another adapter that supports file injection.

Solutions

1. Switch to the Browser Bridge adapter (or any mode supporting setFileInput) as the error message advises
2. Upgrade the browser adapter/driver package to a version that implements setFileInput
3. Check for the capability before running: `if (!page.setFileInput) { /* switch adapter */ }`

Example fix

// before
const page = await connect({ mode: 'cdp-attach' }); // no setFileInput
// after
const page = await connect({ mode: 'browser-bridge' }); // supports setFileInput

if (typeof page.setFileInput !== 'function') {
  console.error('Adapter lacks setFileInput — reconnect with Browser Bridge');
  process.exit(1);
}

const supportsFileInput = (page) => typeof page?.setFileInput === 'function';

try {
  await cli.draft({ video, title });
} catch (e) {
  if (e instanceof CommandExecutionError && e.message.includes('不支持文件注入')) {
    const page = await connect({ mode: 'browser-bridge' });
    await cli.draft({ video, title }, { page });
  } else throw e;
}

When it happens

Trigger: Running `douyin draft` while connected through a browser adapter lacking setFileInput — e.g. a remote/CDP-attached page object, a limited driver, or an adapter version predating the setFileInput API.

Common situations: Using a remote browser session/Bridge-less mode, older adapter versions, connecting to an already-running Chrome via plain CDP, or swapping the default browser backend in config.
