2. Describe the bug

When name is undefined during runtime,
bot.Contact.find({name}) alerts the following error message

ERR Contact this.puppet.contactFindAll() rejected: query only support one key. multi key support is not availble now.

Which is misleading and confusing.

3. To Reproduce

This part is very important: if you can not provide any reproduce steps, then the problem will be very hard to be recognized.

I have made a minimal reproducible GitHub repo

Steps to reproduce the behavior:

• Clone the repo
• Run yarn install
• Run yarn start

4. Expected behavior

The error message tells the user that query key is undefined, or invalid.

5. Actual behavior

The error message tells the user that multi key is not available, which is confusing.

6. Full Output Logs

Set env WECHATY_LOG=silly in order to set log level to silly, then we can get the full log (If you dosen't set log env, log level is info as default, we cannot get the full log)

We need full log instead of log screenshot or log fragments!

$ WECHATY_LOG=silly yarn start

21:14:52 VERB Contact find({})
21:14:52 VERB Contact findAll({})
21:14:52 VERB Puppet contactSearch(query={}, )
21:14:52 SILL Puppet contactSearch() searchIdList.length = 10
21:14:52 VERB Puppet contactQueryFilterFactory({})
21:14:52 ERR Contact this.puppet.contactFindAll() rejected: query only support one key. multi key support is not availble now.
