com.google.gson.JsonSyntaxException

Expected a com.google.gson.JsonObject but was com.google.gson.JsonPrimitive

Samebug tips2

Your json input might be invalid. Try checking it in a validator like https://jsonlint.com

Your custom gson deserializer might have a bug. Try to write a unit test that checks proper deserialization of only that class by forging a json that contains a single field of that type.
