Paypal 3.10.10 - Some orders show payment could not be processed error but it does process

[intandem]

Hi!

 

On a new client installation we have had a few orders recently where the customer goes through the Paypal payment process during checkout but when it reconnects back to Prestashop, they see a message telling them that there was an error and that the payment wasn't processed. They then usually go back and go through the checkout process again. 

 

However, the first payment did in fact go through and an order also gets created in the PS back office. So the customer ends up with 2 orders and 2 payments. 

 

We cannot find anything that the problem orders have in common (different countries, different products etc.). We only noticed in the logs that for the problem order, there are 2 POST events and no GET events afterwards, whereas for normal orders there is 1 POST event and then 4 associated GET events (I've x-ed out shop url and payment IDs):

 

Problem order:
