Key com.symbol.datawedge.decode_data expected byte[]

While working with datawedge scan to intent I am receiving an error which is crashing my Xamarin Android application. The error occurs after scanning a barcode which appears to be a valid barcode with a good read beep. I am adding in some additional logic to handle the null value however I am wondering if this is the expected behavior/value. Testing has been difficult as I am not able to replicate it in house.

This is occurring in a production version of the code and therefor I do not have line numbers, but only have one line in the receiver that is pulling the ByteArray. I believe this is probably happening on the reading of the data as bytes in my broadcast receiver, but am not sure if it is on the creation of the intent from DW.
com.symbol.datawedge.decode_databarcode.DataBytes = intent.GetByteArrayExtra(context.Resources.GetString(Resource.String.datawedge_intent_key_data_bytes));
This is running on an MC3300 with datawedge v. 6.8.50
Here is a snip of the logcat
