What Debezium connector do you use and what version?

I am using debezium server with Postgres connector. Debezium version 2.5.0

What is the captured database version and mode of depoyment?

(E.g. on-premises, with a specific cloud provider, etc.)

Postgres 11, Azure Managed.

What behaviour do you expect?

No exception should be thrown

What behaviour do you see?

Nullpointer exception when storing redis offsets

Do you see the same behaviour using the latest relesead Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)

Yes

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)

2024-05-16 12:17:23,646 WARN [io.deb.sto.red.off.RedisOffsetBackingStore] (executor-thread-5802) Will retry

How to reproduce the issue using our tutorial deployment?

Redis timeout occured when storing offset and then it got stuck in a crash loop of NullPointerException.

Feature request or enhancement

For feature requests or enhancements, provide this information, please:

Which use case/requirement will be addressed by the proposed feature?

Storing debezium offsets to redis store

Implementation ideas (optional)
