Hi, the same thing happened to me using both telegraf and autocert. Any suggestions on how to solve it?

Juju version: 3.5.1-ubuntu-amd64 Terraform version: v1.8.5-dev Juju provider version: v0.10.1 (but also with 0.11.0)

constraints do not apply to subordinate applications

This error is coming from juju itself. Investigation will be need to determine where to fix this issue. It is currently assigned to @jack-w-shaw
