Hi, appery support team!

Is it possible to use $size (Array Aggregation Operator) in order to count and return the total number of items in an array in database? If not, is there any way to accomplish it?

I referenced to the following site.

Hello Sergiy,

Thank you very much for your help.
Now I'm trying to embed your cord into my cord.
I will reply as soon as possible.

I checked it and the result was a specific value like 55486b8de4b03d3319f8ea54.

Hello,

do you have any updated information?

Hello Illya,

I have just changed the setting. Now you can access my database.

Thank you.

Now I shared my app with you.
And, the name of my app is "if" and the name of the service is "Add_1_To_Likes_service".

Thank you.

When I check a line of Put Method, the Response says "-1".
