Consume string messages

[Winand]

When I run docker run --rm --network kafka-netw -v "$(pwd)/zoe:/root/.zoe" adevinta/zoe-cli:0.30.0 topics consume test-topic I get the following error:

failure: runner 'local' failed
cause:
  failure: Unrecognized token 'First': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')
   at [Source: (String)"First message"; line: 1, column: 6]

That's because the string value in a Kafka message is not quoted. Is it by design?

My config file:

---
runners:
  default: "local"
clusters:
  default:
    props:
      bootstrap.servers: "kafka-1:19092,kafka-2:19092"
      key.deserializer: "org.apache.kafka.common.serialization.StringDeserializer"
      value.deserializer: "org.apache.kafka.common.serialization.StringDeserializer"
      key.serializer: "org.apache.kafka.common.serialization.StringSerializer"
      value.serializer: "org.apache.kafka.common.serialization.ByteArraySerializer"
