BOT Error Invalid property identifier character

[Jack_Bates]

I wrote this HTTP body like the one for updating the Inspection Date

This one is for adding the unit to the Maintenance app when a user adds a truck or trailer through the annualloadbook app

Question: What is the Property identifier character?
