[question] Secondary the require secure_forward config? or not support?

Hi,

An error of the 2 will occur in the following the 1 setting file. Is "secondary" not supported in "secure_forward"? Or is it limited to secure_forward?

I am considering using S3 as a fallback destination of "secure_forward" destination.

fluent conf

<match log>
@type secure_forward
secure yes
shared_key "#{ENV['SHARD_KEY']}"
self_hostname "{Socket.gethostname}"
ca_cert_path /path/to/local_ca_cert.pem

<server>
    host receiver
    port 24284
</server>
<secondary>
    type s3
    aws_key_id  access_key
    aws_sec_key secret_key
    s3_bucket my-local-bucket
    s3_endpoint http://minio:9000/
    s3_region us-east-1
    s3_object_key_format %{path}.%{index}.%{file_extension}
    path send_err
    buffer_path /buffer/send_err
    time_slice_format %Y%m%d
    time_slice_wait 1m
    flush_interval 1s # debug
</secondary>
</match>
