Could not parse <field> to 'Date'

[acamillo]

Hi,
I am using v2.0.62 of the library with Kafka connect 6.1.0.

I am trying to parse CSV with values as:
abcd, 2022-01-10T23:09:55.000Z, abcdef, ....

Using this schema

{
  "name": "com.github.jcustenborder.kafka.connect.model.Value",
  "type": "STRUCT",
  "isOptional": false,
  "fieldSchemas": {
    "Log_Source": {
      "type": "STRING",
      "isOptional": false
    },
    "Time": {
      "name": "org.apache.kafka.connect.data.Timestamp",
      "type": "INT64",
      "version": 1,
      "isOptional": false
    },
    "ID": {
      "type": "STRING",
      "isOptional": false
    },
......
  }
}

Connector creation and configuration:

curl -i -X PUT -H "Accept:application/json" \
    -H  "Content-Type:application/json" http://localhost:8083/connectors/ohs-access-csv-spooldir-03/config \

    }'

When running I get the following exception:

Any idea what could be the cause of the issue?
Thank you.

@acamillo Does your csv have a header? I'm wondering if it's actually trying to parse Time with that date format.

[acamillo]

@jcustenborder yes it does have header. However as by recommendation in various blogs I thought to force the schema myself

[jcustenborder]

haha no please use the schema.

Try setting "csv.first.row.as.header":"true" in your config.

[acamillo]

@jcustenborder
yes, that solved the problem. It was actually trying to parse the header line assuming it to be a normal data row.

Thanks for the super fast feedback.

If you don't mind taking a suggestion. The problem would have been much easier to spot (for me) if the exception output did contain the offending data row, that triggered the exception. Maybe in a future release ?
