org.apache.spark.sql.AnalysisException when loading JSON file - json

Question

I've got a large datastore of JSON objects that I'm trying to load into Spark in a dataframe, but I'm receiving an AnalysisException when trying to do any processing on the data. There are several differently formatted JSON objects in the input data. Some of them have the same fields in different orders and/or levels of the JSON.
I've loaded the JSON in with the following code.
val messagesDF = spark.read.json("data/test")
But once I try to perform any operations on the data I receive the following stack trace:

Everything I've been able to find on this error is from joining different dataframes which is certainly similar to what I'm trying to do, but I can't go in and refactor the dataframe to provide unique ids.
