Trouble issuing certs with dns_simply.sh plugin

[S-Groening]

Hi,

I'm new to using acme.sh with the dns_simply.sh plugin and I've run into an issue in relation to certificate issuance with Let's Encrypt.

I want to issue a certificate to a subdomain, but it keeps telling me that the plugin is unable to find the root zone. I've done the splitting of the $fulldomain as the plugin does it and everything splits correctly into $_domain and $_sub_domain, but for some reason the logging tells me that the plugin's trying to use $fulldomain as the root zone, which of course will fail...

The logging tells me the following on the format of the input, which is all correct:

[Mon May 13 12:58:58 BST 2024] Adding txt value: xQcnQq1oz7q-2SRT9DjzC2U6F5wTw4Wq5IrR3KxNeQY for domain: _acme-challenge.unifi.beidemaschinen.de

But right thereafter, the zone handling error occur and nothing goes through with Simply's DNS service, hence nothing passes the Let's Encrypt validation...

What am I doing wrong here?

Steps to reproduce

I installed the latest acme.sh version, entered my account information and ran the command:

./acme --issue --dns dns_simply -d unifi.beidemaschinen.de --debug 2
