This error may occur if you’ve recently created a new vehicle type in Navistream and are now using that vehicle type without assigning an inspection template to it.
To fix this, you’ll need to add your vehicle type to a custom inspection that you’ve created.
Instructions on how to do this can be found in the KB article below:
