How to manage OpenBalena Certificate expiration

I’m making some integration on the previous request.
We tried to set the Production certificate using letsencrypt using the quickstart -c option.
At first we got some errors, but we managed to overcome them thanks to this post:

Commenting the lines 182:183 on cert-provider.sh AND update the Dockerfile to use version 3.0.1 of ACME script “seems” to have solved the installation.
Now the log actually say it has installed a PRODUCTION certificate.

But actually when we test the api.mydomain.com we still don’t have a trusted certificate.
The issuer appear to be (STAGING) Artificial Apricot R3

Why it isn’t a PRODUCTION certificate?
Could we use a self-signed certificate that expires in 100 years?
It’s important to us not to interrupt workload and communications for a certificate expiration, and we will have a lot of devices.

Here is the log from the cert-providers container:

UPDATE:
I still cannot find a solution.
I’ve done

docker system prune -a
docker volume prune
quickstart -U {email} -P {password} -c -d {domain}

But no luck so far…

I’ve connected to cert-provider container and made some tests with the file cert-provider.sh
STAGING certificate does install, but doesn’t verify, so the operation is aborted.
Commenting lines 182:183 as suggested in the other topic skips to the PRODUCTION certificate, but it gives this error:
cat: can't open '/usr/src/app/certs/{domain}/{domain}.cer': No such file or directory

That’s the reason we cannot get a PRODUCTION certificate I guess…
Can someone point me to the right direction?
