Hi! Thank you for raising this.
There seems to be an issue with the MySQL charm. I will check with the team developing the MySQL operator, but meanwhile, could you give it a go to deploy this using Terraform?
YAML are being deprecated in the Juju ecosystem, and the current recommended way to deploy is by using Terraform. We are therefore currently focusing more on providing support for Terraform (with continuous testing and integration with other teams) over maintaining that legacy bundle
Thanks Enrico
