Description
In #2169, I forgot to copy the existing validation for NWC receive to the new code.
This means we didn't check that
pay_invoiceis not supported.Additional Context
I downloaded a CSV file for all currently saved NWC receive protocols to check if any of them do support
pay_invoice. Then we should delete them.I also went through the diff of #2169 to check if I forgot that for other protocols, too, but I didn't. But most of them didn't even include a way to test if payments are not supported (see LNbits, Phoenixd).
This could be fixed via #1341. Instead of only testing if a payment is possible, we can do the same when attaching a receive wallet to make sure it's not possible (we always cancel the HODL invoice).
Checklist
