Kapsel oData Offline plugin request size issue

Hi Experts,

I have developed one hybrid application using SMP with Kapsel oData Offline plugin. Everything is working fine except posting the request with an image.

If I post the request with image size less than 10 KB it works fine but it doesn't work for large image files( not even 100 KB).

The field type I am using as string in oData service in backend system.

Do we have any settings to change the max size for the requests?
