I am getting error while executing this program,
Error:
An object was provided as children instead of a component, string, or number (or list of those). Check the children property that looks something like:
{
“data”: {
“id”: “10.1128/jvi.00747-07”,
“label”: “10.1128/jvi.00747-07”
},
“position”: {
“x”: 75,
“y”: 75
}
}
Can any one help me on this??
