Question
I'm trying to insert a new task in a standard SharePoint task list, this is my item:
var item = {
Title: taskTitle + " - " + subSiteName ,
ProjectId: projectID,
AssignedToId: {'results': [15, 17]}
};
POSTing returns an error 400.
Failed!{"readyState":4,"responseText":"{\"error\":{\"code\":\"-1, Microsoft.SharePoint.Client.InvalidClientQueryException\",\"message\":{\"lang\":\"nl-NL\",\"value\":\"An unexpected 'StartObject' node was found when reading from the JSON reader. A 'StartArray' node was expected.\"}}}","responseJSON":{"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"nl-NL","value":"An unexpected 'StartObject' node was found when reading from the JSON reader. A 'StartArray' node was expected."}}},"status":400,"statusText":"Bad Request"}
Can anyone help me? Thanks in ahead.
Solution
Ensure that allow multiple selections is checked
Also, make sure your json is as below:
var data = {
__metadata: { "type": "SP.Data.TestListItem" },
Title: "Some title",
ProjectId: projectID,
AssignedToId: { 'results': [15,17] }
}
Full code:
var listName = 'Tasks';
var itemProperties = {
'__metadata': { "type": "SP.Data.TasksListItem" },
"Title": taskTitle + " - " + subSiteName ,
"ProjectId": projectID,
'AssignedToId': {"results": [15,17] } //multi-valued User field value
};
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('" + listName + "')/items",
type: "POST",
contentType: "application/json;odata=verbose",
data: JSON.stringify(itemProperties),
headers: {
"Accept": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val()
},
success: function (data) {
console.log(JSON.stringify(data.d));
},
error: function (data) {
console.log(data.responseText);
}
});
Reference - Create task list item with REST API
OTHER TIPS
Please try below code.
var taskProperties = {
'__metadata' : { 'type': 'SP.Data.TasksListItem' },
'Title': 'Order approval',
'AssignedToId' : { { "results": ["4", "7"] } }
};
