NPE when serializer is missing #989
Description
Expected Behavior
There should never be an NPE in serde code.
Actual Behaviour
NPE in this line. Likely deserializer is null.
User reports this happens in conjunction with io.micronaut.serde.exceptions.SerdeException: Cannot find deserializer: class …, with the missing deserializer implementing Deserializer<String>. Likely there is some failure looking up the deserializer, so that it is not set, and then the NPE happens later on. The first error is likely fine, but the NPE should not happen.
Steps To Reproduce
Unclear. No test case currently available. Reproducers welcome :)
