    "incantation": "When a chart uses `lookup()` and rendering needs live cluster values, pass `--template-args=\"--dry-run=server\"` to `helmfile template`, `apply`, or `sync`. `--template-args` forwards extra arguments to Helm rendering.",

      "helmfile template --template-args=\"--dry-run=server\"",

      "Version: v1.7.0",
      "--template-args <string>: Extra arguments appended to Helm rendering; the default is empty. `--dry-run=server` enables a server connection for `lookup()`.",
      "--dry-run=server: Helm server-side dry run; requires cluster connectivity. Pass it as the value to `--template-args` when rendering needs `lookup()`.",
      "Prerequisite: `--dry-run=server` requires cluster connectivity. Helm uses its Kubernetes connection configuration for `lookup()`; API access errors fail template processing."
