how to remove this warning in fluentd? [warn]: #0 Detected ES 8.x or above: document type will not be used

I was running well with efk stack.
Recently I upgraded elasticsearch 7.x to elasticsearch 8.x , there have been 70 warnings per second.
( [warn]: #0 Detected ES 8.x or above: document type will not be used)
how to resolve this problem?
My efk environment :

• elasticsearch 8.6
• td-agent 3.8.1
• os : windows

I don't know well about this message, but it seems to be already fixed at fluent-plugin-elasticsearch 4.3.2

• Use log.debug to dump ES 8.x _type information uken/fluent-plugin-elasticsearch#852

You should try the latest td-agent.
