Magento 2 Payload unable to be handle

I was thinking that Celigo is good enough to handle the large data, a order came in our production system with about 10-15 line and I am keep getting the exceeded payload size error. The question is how much and what data I remove to move this order, how many orders I have to do this?

This is especially happening with pre build IA app.

Are you trying to build this custom or only use the IA? If only the IA, I can move this thread to the Integration Apps category.

I am using the IA app, the integration prebuild app
