[V4] Can't submit large sales orders

I am sitting with a very unusual problem.

I use to submit sales orders with 100+ items but now erpnext refuses to even sales orders with 50 items. It’s time wasting and equally annoying.

What can be done here.

Try Data Import Tool, here is the link

Hi @Venky_78! Did you got an error prompt or any traceback from the console? Let us know. Thanks!
