Kafka - Connect

You have this transform chain:

transforms=InsertField
transforms.InsertField.type=org.apache.kafka.connect.transforms.InsertField$Value
transforms.InsertField.field=source
transforms.InsertField.value=app1

But the connector fails to start. What is the likely error?

AIncorrect property name: should be 'static.field' and 'static.value' under 'transforms.InsertField'

BMissing 'transforms.InsertField.field' property

CInsertField transform does not support static fields

DThe transform type is invalid

Step-by-Step Solution

Solution:

Step 1: Check property names for InsertField
The correct properties are 'transforms.InsertField.static.field' and 'transforms.InsertField.static.value'.
Step 2: Identify error cause
If these are misspelled or misplaced, the connector fails to start due to invalid config.
Final Answer:
Incorrect property name: should be 'static.field' and 'static.value' under 'transforms.InsertField' -> Option A
Quick Check:
Property names must match transform config keys exactly [OK]

Quick Trick: Check exact property names for transforms to avoid startup errors [OK]
