Resolved Error with Buckaroo payment

After a payment with Buckaroo I get an error: No log ID has been found
See the attached screenshot
The strange thing in this situation is that I receive a confirmation email without the Buckaroo payment (pay cash at pick up).
What happened:
- I ordered a product
- After the checkout form I'm on the Buckaroo site to select a bank for the iDeal payment
- The money is transfered from the bank account
- The browser sends me back to the webshop and displays the attached error

But why? I have a status page menu item.
In Admin Tools /cli/notify.php is allowed, but when go to the url in the browser the error is "No log ID has been found"
I didn't see any clue in the transaction log, but maybe you understand what goes wrong (see attachment)

Thank you in advance,
With kind regards,
Robert
