HTTP Request Framework7 v5

Hi,

I have a problem with my Framework7 app,
I want to send data to my API using http request :

        app.request.promise({
          url: 'https://www.xxxx.com/aaa/bbb',
          method: 'post',
          data: {
            param1: 'param1',
            param2: 'param2',
            param3: [{x:'a'},{x:'a'},{x:'a'},{x:'a'},{x:'a'},{x:'a'},{x:'a'},{x:'a'}..{70 datas}],
          },
          dataType: 'json',
        })

But when its executed, its only send 50 of 70 objects from param3.
Is there any config that I should add in my code?

Thank you.
