freeznet opened a new issue, #15667: URL: https://github.com/apache/pulsar/issues/15667
**Describe the bug** For some of the source connectors, like debezium connector, it actually not sending any messages to the `topicName`. And the `topicName` cannot be null: https://github.com/apache/pulsar/blob/branch-2.10/pulsar-functions/utils/src/main/java/org/apache/pulsar/functions/utils/SourceConfigUtils.java#L296-L298 But from the java instance, if no topic is provided, it will use [PulsarSinkDisable](https://github.com/apache/pulsar/blob/branch-2.10/pulsar-functions/instance/src/main/java/org/apache/pulsar/functions/sink/PulsarSinkDisable.java) instead. We should remove the strict validation on `topicName` for the source connector. **To Reproduce** Steps to reproduce the behavior: 1. Go to '...' 2. Click on '....' 3. Scroll down to '....' 4. See error **Expected behavior** A clear and concise description of what you expected to happen. **Screenshots** If applicable, add screenshots to help explain your problem. **Desktop (please complete the following information):** - OS: [e.g. iOS] **Additional context** Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
