we can't process express checkout approval

[wasim007]

We have integrated PayPal express checkout in magento 2.3.2.

Customer getting error : "we can't process express checkout approval"

customer trying to purchasing online product (online course)
payment was deducted with PayPal and return back chekout page and show this error "we can't process express checkout approval"

on checkout page not redirecting on thank you page that's why magento order process not completed.

Note: it's working fine with "simple product" and "downloadable product" it's giving error with "virtual product"

Please look into this on high priority and resolve ASAP.
we have checkedat our end there and no issue found in magento the issue with paypal side.

we also verify log files "payment.log" and others log no error found.

Anyone have any ideas for this?
I am stuck and can't process transactions

Using Magento 2.4.2

payment isn't processed when I go to checkout and choose paypal.

Using express checkout from the product page gets me this error:  We can't place the order.

Magento 2.4.2

In my case it turns out it was a instore pickup extension that I installed.

To find out what it was, this is what I did.

Under stores > configuration > sales > payment method > PayPal configure > Advanced Settings

Set Debug mode to Yes

And just in case it helps

Under stores > configuration > sales > payment method > PayPal configure > PayPal Billing Agreement Settings

Set Debug mode to Yes

Check your system log in var > log

And payment.log is here if you want some info on the PayPal transaction

This is the error I got

main.CRITICAL: Exception message: Notice: Undefined index: in  /public_html/app/code/FME/StorePickup/Observer/SavePickUpObserver.php

To test, I turned off all delivery methods except Flat rate and then I was able to process an order.
