[Lenses/kafka] Fix the problem “Cannot extract connector information from the configuration provided” when creating connector Kafka-connect

Nếu bạn sửa dụng kafka-connect mà sẽ cần add thêm rất nhiều plugin vào server kafka-connect.
Mình đang gặp vấn đề có 1 vài plugin lenses ko thể validate được.

Ví dụ như plugin này: MongoDB Connector (Source and Sink)

khi mình create 1 connector có hiện tượng sau:

Cannot extract connector information from the configuration provided.
Lenses kafka

Lenses can’t validate a few plugin of Kafka-connect

Có 1 người anh chỉ mình:
https://docs.lenses.io/5.0/configuration/static/options/topology/#configure-lenses-to-load-a-custom-connector

chúng ta cần Configure Lenses to load a custom connector

Nếu bạn chạy docker compose thì

version: '3'
services:
  lenses:
    image: lensesio/lenses:latest
    container_name: lenses
    ...
    environment:
      ...
