Stripe error: Payment for PaymentIntent was not found & Invalid signature for Stripe webhook

[amityweb]

Does anyone know where to start debugging this, I just can't figure it out. If I pay on Saleor using a manual payment, no card, its all OK, order created. If I pay using Stripe, Stripe takes the payment successfully, the webhook is called, but in the Saleor logs there are errors, and no order is created in Saleor. The payment is in Saleor's DB still with status "NOT_CHARGED" (it does not show in the admin, I have to find it there in the admin).

I'm just not sure what the issue is.

Payment for PaymentIntent was not found -> the payment is in the database. what connects the Stripe webhook call to the payment in the database, maybe there is some info like an ID missing?
Invalid signature for Stripe webhook -> I don't know how to sort this out, Saleor auto creates the webhook and end point and all thats setup OK.
