Welcome!

• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you do?

I want to write a plugin for Traefik and need to send the content through Kafka, but I got an error when importing the Kafka package, here is my code.

package pluginmirror2kafka

import (
	"context"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"net/http/httptest"
	"sync"
	"text/template"

	"github.com/IBM/sarama" 
)

traefik --configFile=traefik.yml

Yes, I also raised this issue, so I asked here because no one solved it.

Obviously, the traefik/traefik answer should be a little more positive.I hope to be able to solve the problem here
