API Contact > GetValue Javascript Incorrect for Custom Value

The code generated for JavaScript when trying to get a custom value is not correct. It puts the return into brackets which causes the javascript to have an error.

Here is the generated code:

CRM.api3('Contact', 'getvalue',

{ "sequential": 1, "return": ["custom_102"], //custom_fieldId "id": 2 // contact id }

).done(function(result)

{ // do something }

);

Here is the error:

Object

{ invalid_field: Array[1], is_error: 1, error_message: "field Array unset or not existing" }

error_message : "field Array unset or not existing"
invalid_field : Array[1]
0 : "custom_102"
