Getting "Unable to get public no-arg constructor" When Using "logstash LogstashEncoder" - json

Question

I'm trying to configure a Spring Boot project to use net.logstash.logback.encoder.LogstashEncoder to format log output in JSON and provide the ability to use the keyValue method for adding custom fields to the output. I know there are other ways of doing it, but many of our current applications using an older version of Spring use this technique and it works well. In order to update those applications, we'd like to be able to use the same configuration.
The problem I'm having is that with the following logstash.xml file:
<configuration>
<appender name="json" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
</appender>
<root level="INFO">
<appender-ref ref="json" />
</root>
</configuration>
I'm getting the following error when starting the app:

If I look in com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module, there is a public no-arg constructor.
Relevant dependency versions:
Spring Boot*: 2.7.2
Jackson*: 2.13.3 (managed by Spring Boot)
Logback*: 1.2.11 (managed by Spring Boot)
Any thoughts on what I could be doing wrong?

Turns out this was an incompatibility between logstash-logback-encoder and jackson-datatype-hibernate5. Whenever I try to use the logstash encoder with jackson-datatype-hibernate5 on the classpath, the error occurs. I've raised an issue in the logstash github repo here: https://github.com/logfellow/logstash-logback-encoder/issues/878
