Bug in Paypal module when not having a correct paypal account

-- HikaShop version -- : 4.4.0
-- Joomla version -- : 3.9.23
-- PHP version -- : 7.4.12
-- Error-message(debug-mod must be tuned on) -- : Invalid Merchant or Merchant doesn't exist!

I came into this bug: after activating the Hikashop Paypal advanced payment plugin and NOT YET HAVING a correct paypal account, the problem is that the enduser will receive an error (which is correct) during the checkout process, but the shop owner is receiving a confirmation that all is well.
Haven't yet tested so I don't know what will happen when I have a correct Paypal environment installed and something goes wrong.
Eitherway: how can I prevent that the shop-owner is receiving an "all-well" confirmation regarding the payment via Paypal in this false environment?

1)in the overview of the orders (back-end), this order has a status that it is paid correctly via Paypal.
2)The final client has received a confirmation by e-mail that all is paid (correctly) via Paypal although he has seen on the screen that there was an error with the paiement.
Any suggustion to change this? Certainly preventing the customer having a confirmation that all is being paid...

Exact: the payment method is configured wrongly in HikaShop. I know that.

Hello,

Good, so the order wasn't confirmed but from what you said through your first message, the shop-owner is receiving an order confirmation email. Can you show us screenshots of one of these emails so that we can find out which email was sent ? Thank you.

You can check every email sent by your shop via "Hikashop->Customers->Email history".

Kind regards,
Mohamed.

Are you saying now that when one is receiving an order with the status 'created', the owner of the shop must control his bankaccount before knowing that all is right?
And what to do with a 'created' order where the payment wil happen locally in the shop when the goods are being received?

That is difficult to understand. Certainly for someone who is working part-time at the shop. In 1 situation 'created' = ok, go for it; and in another situation 'created' = STOP

Anyway, I was just saying that in my opinion it is a bug. How you are dealing with this info, is up to you. It was my mistake because the Paypal account is not correctly activated. If I have, with a correct configured Papal account the same problem, I'll come back with a detailed explanation.

PS the same e-mail as always is being used with the confirmation of the order. And this for the end-user and the shop owner.
