Description

What happened?

Serializing a ServiceException with a non-string object as the value of an Arg serializes the value of the arg as a JSON string instead of a proper JSON object (seems to happen in SerializableError.forException where the toString representation of the object is used, as opposed to the proper JSON object) - for example SafeArg.of("param", ImmutableList.of("arg1", "arg2"))

This is a problem since it's a mismatch between what the consumer of the exception expects (JSON object) and the actual JSON value (JSON string containing the toString representation of the object)

What did you want to happen?

Convert the safe-arg value to a proper JSON object, since that is what the consumer code expects.

Research direction

Start in errors/src/main/java/com/palantir/conjure/java/api/errors/SerializableError.java at SerializableError.forException, using SafeArg.of("param", ImmutableList.of("arg1", "arg2")) as the reproduction. Trace how the non-string value is serialized and verify that the resulting error JSON contains an object rather than a string containing its toString representation.
