Hi @arunx2 , I think it need to make a minor adjustment of adding `_ "github.com/benthosdev/benthos/v4/public/components/opensearch"` import to the [public/components/all/package.go](https://github.com/arunx2/benthos/blob/opensearch/public/components/all/package.go) file, so that `cmd/benthos/main.go` cli can include the opensearch output....
