# CONFIG_INVALID_ARGUMENT

**Invalid argument passed to a primitive**

## What happened

A function was called with an argument that fails a precondition (wrong type, out of range, empty value, etc.). The error message names the specific field.

## How to fix

Read the error message — it always says exactly which argument and what the constraint is. If you're integrating via the CLI, double-check the flag value.

## Example

```ts
try {
  // ...
} catch (e) {
  if (e instanceof ZeroGError && e.code === "CONFIG_INVALID_ARGUMENT") {
    console.error(e.message, e.hint);
  }
}
```
