Description

When I try to run the the reset tool with --to-datetime, such as:

 

kafka-streams-application-reset.sh --application-id "my-service" --bootstrap-servers 1.1.1.1:9092 --input-topics "my-topic" --to-datetime '2022-02-12T23:27:00.000' --execute

 

I get the following exception

Reset-offsets for input topics [my-topic] Following input topics offsets will be reset to (for consumer group my-service) ERROR: java.lang.NullPointerException: Cannot invoke "org.apache.kafka.clients.consumer.OffsetAndTimestamp.offset()" because the return value of "java.util.Map.get(Object)" is null java.lang.NullPointerException: Cannot invoke "org.apache.kafka.clients.consumer.OffsetAndTimestamp.offset()" because the return value of "java.util.Map.get(Object)" is null at kafka.tools.StreamsResetter.resetToDatetime(StreamsResetter.java:506) at kafka.tools.StreamsResetter.maybeReset(StreamsResetter.java:448) at kafka.tools.StreamsResetter.maybeResetInputAndSeekToEndIntermediateTopicOffsets(StreamsResetter.java:397) at kafka.tools.StreamsResetter.run(StreamsResetter.java:167) at kafka.tools.StreamsResetter.run(StreamsResetter.java:135) at kafka.tools.StreamsResetter.main(StreamsResetter.java:665)

Note when I run the above with --to-earliest or --to-offset instead of -to-datetime, the tool runs successfully.
