no String-argument constructor/factory method to deserialize from String value, when trying to deploy a debezium connector

Question

I'm following along with a video tutorial for kafka connect and he wants me to deploy a debezium connector using the following curl command in cmd:

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" 
localhost:8083/connectors -d """{
    "name": "articles-connector", 
    "config": {
        "connector.class": "io.debezium.connector.mysql.MySqlConnector", 
        "tasks.max": "1", 
        "database.hostname": "mysql", 
        "database.port": "3305", 
        "database.user": "globalmantics", 
        "database.password": "password", 
        "database.server.id": "223344", 
        "database.server.name": "globalmantics", 
        "database.whitelist": "globalmantics", 
        "database.history.kafka.bootstrap.server": "kafka:9092", 
        "database.history.kafka.topic": "schema-changes" 
    } 
}"""

However when I run that command I get the following error:

HTTP/1.1 500 Internal Server Error

Any ideas on what I'm doing wrong?

Answer 1

You need to remove the triple quotes. Use single quote around the JSON.

Or use a file.

curl -X POST \
  -H "Content-Type:application/json" \
  -d@connector.json \
  localhost:8083/connectors
