[Bug]: Error LNURL payment link on creating invoices over API

[ndeet]

What is your BTCPay version?

v1.12.5

How did you deploy BTCPay Server?

Umbrel

What happened?

A user reported that he gets this error when invoices are created through API via WooCommerce:

"Error generating LNURL payment link: serviceUrl must be an onion service OR https based OR on the local network (Parameter 'serviceUrl')

Seems this is related to Umbrel setup and not a general problem as I was not able to reproduce it.

This can be fixed by disabling LNURL in the LN wallet settings.

How did you encounter this bug?

Running on BTCPay on Umbrel and creating an invoice over the API (in this case WooCommerce plugin)

Relevant log output

Error generating LNURL payment link: serviceUrl must be an onion service OR https based OR on the local network (Parameter 'serviceUrl')

What browser do you use?

No response

I don't quite understand, is this a problem with Umbrel only, do we know how to resolve this?

[ndeet]

To me it looks like the error happens because on Umbrel the setup is missing LNURL support or some endpoint not reachable - nothing we can do there. But we may can do some check if LNURL is available and avoid the error and just silently ignore it to solve he issue.
