Failed to save configuration: ${error instanceof Error ? err

Error message

Failed to save configuration: ${error instanceof Error ? error.message : 'Unknown error'}

What it means

handleSaveConfig's catch-all: the save workflow failed while merging the existing config or during fs.writeFile of the JSON payload. The underlying filesystem or serialization error's message is wrapped and rethrown so the caller knows why the write did not land.
