## Common Errors

### 400 Bad Request

**Cause:** Missing required fields or invalid data

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "field required",
  "code": "MISSING_REQUIRED_FIELD"
}
```

**Solution:** Ensure all required fields are provided: `name`, `responsible_user_id`.

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Invalid API key",
  "code": "INVALID_API_KEY"
}
```

**Solution:** Verify your API key is valid and active.

### 422 Validation Error

**Cause:** Invalid field values

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body", "end_date"],
      "msg": "end_date must be equal to or after start_date",
      "type": "value_error"
    }
  ]
}
```

**Solution:** Check that:

* `end_date` is equal to or after `start_date`
* `responsible_user_id` is a valid UUID
* `project_type` is one of the allowed values
* `methodology` is one of the allowed values
