Hey guys, I am introducing http4k in a project at work and I somehow get an error when serializing with Jackson in my http client:

java.lang.NoSuchMethodError: com.fasterxml.jackson.module.kotlin.KotlinModule

I am using versio

2.10.2

of

com.fasterxml.jaclson.module

and version

4.8.0.0

of http4k. How can I fix this?

🙂

I know that, but I try to integrate it in a project where jackson was already present ..

aha - ok. 🙂 . Jackson does tend to have incompatibilities which end up with this type of thing. Also worthy of caution is when the version of Kotlin-reflect JAR varies because that also affects things. And playing with a Kotlin 1.5.0 upgrade yesterday also threw up a few potentially worrying bits around this.. 🙄

haha I can imagine! If I see weird things I will pop-up again! Thank you for your help
