...ANSWER
Answered 2021-May-11 at 13:32You're using spring-data-redis 2.3.9

The support of Streams with Jedis is only available from 2.5.0

There is an application written with Spring Boot 1.5.21. I'm asked to upgrade it to Spring Boot 2.3.4, and fix the errors the upgrade brings. Apparently, this didn't go well since I'm merely a beginner on many things. I've been able to solve some errors due to dependency changes, by googling.

ANSWER
Answered 2020-Aug-12 at 19:00you didn't set a key serializer, so it uses the JDK serializer as default. So the key was not actually stored as String in Redis server.
Change your code in the config about redis to this and try again.
