Error after selecting delivery method and filling in adress

Hi,

I get this error after I select the delivery method and I fill in the adress details and I click on next:
“Sorry!
Er ging iets mis tijdens het verwerken van uw order.
Gelieve het later eens opnieuw te proberen.
Ga terug naar de webwinkel.
”

Do you know what is wrong? Thank you in advance.

This is the errorlog:
