I’m using Azure Devops CI/CD pipeline, running liquibase 4.29.1 docker image to update our MS SQL Server resource hosted in Azure and I’m receiving the following error. I have the liquibase-azure-deps-4.29.1.jar mounted to /liquibase/lib. My connection string is authenticating as Authentication=ActiveDirectoryManagedIdentity.

I was able to connect using a service principal, `Authentication=ActiveDirectoryServicePrincipal`
