# Which Problems Are Solved Corrects reading of default configuration, despite reading all default configs only required defaults are read. # How the Problems Are Solved Reading the defualt config of the `mirror`-command was moved to a pre-run step of the command instead of doing it during initialization of the executable. # Additional Context - Closes https://github.com/zitadel/zitadel/issues/8059 - https://discord.com/channels/927474939156643850/1248594307267559535
