Here is the html text of my widget :
<!DOCTYPE HTML>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
window.onload = function () {
$.ajax({
url: "/OperationsManager/data/scomGroups",
type: "POST",
headers: {
"Content-Type": "application/json"
},
data: {
"criteria":"DisplayName = '_ITER_RDS_CATIADesigners_Computers'"
},
success: function (result) {
alert(result);
},
error: function (jxhdr, exception) {
alert(jxhdr.status);
alert(jxhdr.responseText);
alert(exception);
}
});
}
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/canvasjs/1.7.0/canvasjs.min.js"></script>
</head>
<body>
</body>
</html>
at execution, error function is called and jxhdr.responseText is equal to :
{errorMessage: "Passed parameter cannot be null",
errorTrace: ""}
Can anybody help me on this topic ? Thank you by advance
