Issue ssl certificate generate by lua error like urn:acme:error:malformed

I have an issue on my server when ssl generate by openresty and my server down. The error like,'

err: + ERROR: An error occurred while sending post-request to https://acme-v01.api.letsencrypt.org/acme/new-authz (Status 400)

Details:
{
"type": "urn:acme:error:malformed",
"detail": "Error creating new authz :: Domain name ends in a dot",
"status": 400
}

One of the domain have wrong and it cause issue. Can you please how to resolve this wrong domain. Any way we can check the domain and reject it.

Currently my implementation is:
auto_ssl:set("allow_domain", function(domain)
return true
end)

Please help me to resolve ASAP.

Start at the auto_ssl:set("allow_domain", ...) callback shown in the issue and trace how its result reaches the Let's Encrypt new-authz request. Reproduce or inspect handling for a domain ending in a dot; done should include rejecting or safely handling that invalid domain before the ACME request, with the server remaining available.
