Not parsing embedded json arrays #151

I was parsing a file but I simplified to a string for the example. When reading the file I got a somewhat different casting exception from JsonArray to JsonObject. Here is the full stacktrace from the screenshot:

class java.lang.String cannot be cast to class com.beust.klaxon.JsonObject (java.lang.String is in module java.base of loader 'bootstrap'; com.beust.klaxon.JsonObject is in unnamed module of loader java.net.URLClassLoader @64d1cb43)
java.lang.ClassCastException: class java.lang.String cannot be cast to class com.beust.klaxon.JsonObject (java.lang.String is in module java.base of loader 'bootstrap'; com.beust.klaxon.JsonObject is in unnamed module of loader java.net.URLClassLoader @64d1cb43)

Could you post the example as text?
