packageInfo.template 必须是 'package' 或 'plugin'

Error message

packageInfo.template 必须是 'package' 或 'plugin'

What it means

validateExecutionPlan requires that packageInfo.template, when package creation is requested, is exactly "package" or "plugin" — the same enum as the top-level packageType, because this field drives the code-generation template selection. Other values (including different casing) are rejected.

Solutions

  1. Set packageInfo.template to exactly "package" or "plugin" (lowercase).
  2. Sync it with the top-level packageType (they must match — see error 23).
  3. Normalize/validate the value against the whitelist before sending.
  4. Ensure the source of the value (form/config) only offers these two options.

Example fix

// before
packageInfo: { packageName: "order-center", template: "Plugin", label: "订单中心", desc: "..." }

// after
packageInfo: { packageName: "order-center", template: "plugin", label: "订单中心", desc: "..." }
Defensive patterns

Strategy: validation

Validate before calling

function requireValidNestedTemplate(plan) {
  if (plan.needCreatedPackage && !['package', 'plugin'].includes(plan.packageInfo?.template)) {
    throw new Error(`packageInfo.template must be 'package' or 'plugin', got: ${plan.packageInfo?.template}`);
  }
  return plan;
}

Type guard

function hasValidNestedTemplate(plan) {
  return !plan.needCreatedPackage || plan.packageInfo?.template === 'package' || plan.packageInfo?.template === 'plugin';
}

Try / catch

try {
  return await callTool('gva_execute', { executionPlan: plan });
} catch (err) {
  if (String(err.message).includes("packageInfo.template 必须是")) {
    const normalized = String(plan.packageInfo.template).toLowerCase();
    plan.packageInfo.template = ['package', 'plugin'].includes(normalized) ? normalized : plan.packageType;
    return callTool('gva_execute', { executionPlan: plan });
  }
  throw err;
}

Prevention

When it happens

Trigger: executionPlan with needCreatedPackage=true and packageInfo.template set to "", "Plugin", "module", or any string other than the exact lowercase literals "package"/"plugin".

Common situations: UI dropdown defaulting to an empty value; LLM writing a human-friendly template name; older plan format using different template identifiers that no longer match the whitelist.
