Spring boot 3.1.4 java 17 and axon 4.8

I am using jackson serializer but still getting below error

Hey @Piyushdubey8!

Would you be able to share how you have configured the JacksonSerializer within Axon at this moment?

Furthermore, sharing the full stack trace would help to pinpoint from which infrastructure component in Axon Framework the issue originates.
So, if you could share the full trace, that would be great.

A potentially quick solution to pinpoint which component you missed replacing the Serializer would be to exclude the xstream dependency from your project.

Nonetheless, if you’re willing to share, I would like to help you further finetune the configuration. :slight_smile:
