Fix Kafka SMT kamelets for CAMEL-23584 header rename#2875
Merged
Conversation
CAMEL-23584 renamed all camel-kafka Exchange header constants from
kafka.* to CamelKafka* prefix. Two kamelet YAML definitions still
used the old names, causing silent failures:
- topic-name-matches-filter-action: ${header[kafka.TOPIC]} → ${header[CamelKafkaTopic]}
- timestamp-router-action: timestampHeaderName default kafka.TIMESTAMP → CamelKafkaTimestamp
