LogError

[Yultek]

Hey there, ive been attempting to use the json exporter and i keep receiving

this error report. Not sure if im missing a step.
-I have not added a sound path to the modifier
-I have selected each object in my assets and added the modifier, not sure if i have to do the same for each individual child object within the main object.
-I have not removed the camera from the original shot.
Let me know what i may be doing wrong here, thanks!
