Adding a description/comment to a workorder when creating it.

I understand that a description is supposed to be a "Comment" node in the items array. I think I have this formatted correctly, however the resulting work order does not contain that comment/description that has been submitted. Is this the correct place for the comment?

{
"Command":{
"WorkOrder":{
"Items":[
{
"Asset":{
"Id":42679
},
"Task":{
"Id":14477
},
"Comment":"Deli:B2 CLR is to warm at 45.9 \nhttps://monitor.envirowatchsolutions.com/sensors/detail/o3IGgwzj \nplease look into this\nSavemart/Save Mart 049/Deli:B2 CLR is to warm at 45.9\nhttps://monitor.envirowatchsolutions.com/sensors/detail/o3IGgwzj"
}
