GoCardless Payments not working

[torstenhoegel]

Hello there,

my setup is in the Frappecloud:

I've added a GoCardless account:

What I tried is to setup an invoice and added a payment request with the payment gateway account added.
What happened next:
I've received an email:

As you can see, there's no payment link .. anything else I have to setup for this to work?

I also checked the mandate list but it's empty, although I have added one manually in GoCardless. Is it supposed to show up here?

The last thing I tried was to setup an portal customer account and access the invoice there.
It shows up (with the GoCardless Setting):

but when clicking on it there's an error:

Traceback (most recent call last):
