Query array of values - Removing objectId (type string ) from array of strings #3144

Hi,

I'm hosting Parse server on Heroku. My issue is when I'm removing an objectId from array of strings. I have a cart column (array) on JobFeed class. I query the following:

$http( {
method: 'PUT',
url: 'https://myserver/1/classes/JobFeed/' + jobId,
data: {
cart: {
__op: 'Remove',
objects: [ service.objectId]
}
}
});

It returns JobFeed with the objctId still on the array.
