Spring boot redis session : Failed to serialize object using DefaultSerializer: StandardServletEnvironment.class

I am having a problem while serializing one of my session beans in redis.

Caused by: org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.io.NotSerializableException: org.springframework.web.context.support.StandardServletEnvironment

I do not use StandardServletEnvironment and found no usages of it.I use default JdkSerializationRedisSerializer serializer
