Error message

找不到 ${fieldName} 输入框，截图已保存到 /tmp/wechat-channels_publish_${fieldName}_debug.png

What it means

fillField runs an in-page script that traverses shadow DOM to find a field among the given selectors, fills it, and verifies the value. If it cannot find/fill/verify, it saves a debug screenshot to /tmp/wechat-channels_publish_<fieldName>_debug.png and throws CommandExecutionError naming the field. This indicates the form field was not reachable in the current page state.

Solutions

Inspect /tmp/wechat-channels_publish_<fieldName>_debug.png to see the actual page state.
Confirm login is valid and the create page rendered fully before the fill step.
Retry — transient slow rendering can miss the field; add/rely on wait before filling.
Update TITLE_SELECTORS / DESC_SELECTORS in clis/wechat-channels/publish.js to match the current DOM from the screenshot.

Example fix

// before
const TITLE_SELECTORS = ['input[placeholder*="短标题"]'];
// after (selector observed in debug screenshot)
const TITLE_SELECTORS = ['input[placeholder*="短标题"]', 'input.weui-desktop-form__input[placeholder*="标题"]'];

Defensive patterns

Strategy: try-catch

Validate before calling

null

Type guard

null

Try / catch

try {
  await publish({ videoPath, title, description });
} catch (e) {
  if (/找不到 .* 输入框/.test(e.message)) {
    const m = e.message.match(/\/tmp\/wechat-channels_publish_(.+)_debug\.png/);
    console.error(`Form field missing (${m?.[1]}); inspect screenshot, check login, retry`);
  }
  throw e;
}

Prevention

Ensure the session is logged in and the create page fully rendered before publishing.
Review the per-field debug screenshot after any failure.
Re-validate TITLE_SELECTORS / DESC_SELECTORS whenever WeChat updates the creator UI.
Fix earlier step failures (upload) first — they can leave the form without input fields.

When it happens

Trigger: Title (短标题) or description (添加描述) selectors no longer match after a WeChat UI update; the form never rendered because of an expired login or earlier step failure; page still loading when fillField ran.

Common situations: WeChat redesigning the creator form; session redirecting to login; contenteditable structure changed; a prior upload failure leaving the form in a state where fields are absent.
