我正试图从海妖补充一对。但是我得到了这个错误：
blade@debian:~/zenbot$ zenbot backfill kraken.XXBT-ZEUR --days 1node-telegram-bot-api deprecated Automatic enabling of cancellation of promises is deprecated.
In the future, you will have to enable it yourself.

我尝试过使用gdax，但它确实有效。问题出在哪儿？ zenbot或kraken？
当我在status.kraken.com上看到图片时，他们的API似乎有效。
