Failed to update setting: invalid synchronized_output '{valu
Error message
Failed to update setting: invalid synchronized_output '{value}'. Expected: auto, on, off. What it means
Validation failure in the settings update path: the value supplied for the synchronized_output setting was not one of the three accepted keywords auto, on, or off after normalization. A generic enumerated-value guard; fires on typos or unsupported values passed to the setting updater, mirroring the adjacent status_indicator check.
