[BUG] Unable to Autowired : Field mapper in example.Application required a bean of type 'com.fasterxml.jackson.databind.ObjectMapper' that could not be found.
See original GitHub issueDescribe the bug When I receive a Event my function starts, but there is an error when trying to @Autowired an ObjectMapper.
Exception or Stack Trace
2022-11-24 16:49:39.350 WARN 93 --- [pool-8-thread-3] o.s.c.support.GenericApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'application': Unsatisfied dependency expressed through field 'mapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.fasterxml.jackson.databind.ObjectMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
To Reproduce Just upload a blob item and the event will be received.
