Paypal, We can't place the order error- Magento 2

[prema_mani1]

Hi,

I am getting "We can't place the order error" error in paypal/express/review/ page, while placing order. It is not even throwing any error in system.log file.

Please help me to fix this issue!

Hi @prema_mani1

Have you customized your Magento 2 store? If the answer is yes, the error is very likely to be caused from the configuration. It can be also caused from your custom module.

Hi,

Finally, I found solution for the issue,

Everything works perfect in magento as well as in Paypal configuration.

The issue is foreign key check disabled in Database, while importing order data. These data contains inconsistent values in sales_order_item table.

After deleting those inconsistent values and enabling foreign key check, it works perfect.

Thank You!
