I'm trying the Ignition SDK examples, especially the Perspective Components example.

What would be the proper default value for Dataset props in .props.json? I tried null, {}, , [] values but all of them seems to be giving error like: null found, expecting dataset.

{  
"type": "object",  
"properties": {  
"data": {  
"type": "Dataset",  
"default": null,  
"description": ""  
},
