Errors when reading a lookup field of a list item using the JavaScript Object Model

Question

I changed a field from being a single line of text, to being a lookup (still only displaying a single line of text, but it's fetched from another list. The field's internal name is Status. This is where I get an error:

oListItem.get_item('Status');

The error reads:

The property or field has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

So I changed this line

clientContext.load(listItemCollection);

to

clientContext.load(listItemCollection, 'Include(Status)');

Now, the executeQueryAsync's failure handler is called with the following error:

Value does not fall within the expected range.

Any ideas what might be causing this? The code worked before I changed the column type, so the problem shouldn't be with any other code...

Edit:

Based on Dikesh Gandhi's suggestion, I tried adding the following to my caml query:

<View><ViewFields><FieldRef Name="Status" /></ViewFields></View>

But then the original error (not initialized) returned, regardless of if I have the include-string passed to the load function.

Answer 1

It seems there can be few causes as mentioned below.

1. Use of invalid field name. You need to use the internal field name!
2. Change the List View Lookup Threshold value of the web application. Default value is 8.

Answer 2

Is that column is lookup and display type ? please check column name in list seetings as columnName:title. If so need to change the column reference

Answer 3

Are you on 2010 or 2013?

Status is the internal fieldname of SharePoints default Task Status feld on 2013

So if you create a new Field Status it will be Status0 (or was it 1 ?) for the Internal Name
