BUG - ACME plugin automation not working

[stefan21]

OPNsense 23.7.7_3-amd64
FreeBSD 13.2-RELEASE-p3
OpenSSL 1.1.1w 11 Sep 2023
ACME Client 3.19

I reset the acme plugin and created a new cert and a new automation. SFTP upload test is giving no errors.

But a manual run of an automation (ACME client --> Services: ACME Client: Certificates --> run automations causes in following error:

AcmeClient: automation not found: b2a9610b-7fb3-4554-bf4e-09eaa77c65eb

No matter after copying the automation in a new one, or deleting the automation and creating a new one. All new or copied automations always have the same ID b2a9610b-7fb3-4554-bf4e-09eaa77c65eb.

How to investigate? Any advice is appreciated.
