# File id missing · file.id\_missing

Canonical page: https://errorgram.rmbk.me/errors/file.id_missing/

**Stable ID:** `file.id_missing` · **Evidence:** observed

The file\_id argument is missing or empty.

This response concerns a missing file identifier; it does not validate an upload or a nonempty identifier.

## When it matches

Every field in a rule must match. Alternative rules are joined with OR.
Codes below are JSON response fields, not inferred HTTP statuses.

- JSON `error_code`: **400**.

Exact description:

```text
Bad Request: file_id not specified
```

See [matching rules](https://errorgram.rmbk.me/matching/) for parameter precedence
and unknown or ambiguous results.

**Illustrative methods:** `getFile`.

## Possible causes

- The remote-file lookup received an empty file\_id.

## Before deciding what to do

**Application decision:** supply file identifier.
**Repeat request:** after relevant change.

- Use the file\_id supplied for this bot by Telegram, rather than file\_unique\_id.

These are application choices. Errorgram does not retry, suppress the error,
or change bot state.

## Facts

This condition adds no extracted facts; `result.facts` is empty.

## Example

Synthetic examples derived from the cited source.

API method: `getFile`.

```json
{
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: file_id not specified"
}
```

### Python

```python
from errorgram import classify

response = {
    "ok": False,
    "error_code": 400,
    "description": "Bad Request: file_id not specified",
}
result = classify(response, method='getFile')

assert result.id == 'file.id_missing'
print(result.entry["summary"])
```

### JavaScript and TypeScript

```ts
import { classify } from "errorgram";

const response = {
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: file_id not specified"
};
const result = classify(response, { method: "getFile" });

if (result.status === "matched" && result.id === "file.id_missing") {
  console.log(result.entry.summary);
}
```

## Framework names

| Integration | Type or ID |
| --- | --- |
| Python | `errorgram.FileIdMissing` |
| aiogram | `errorgram.aiogram.FileIdMissing` extends `TelegramBadRequest` |
| grammY | `EnrichedGrammyError` with `classification.id` equal to `file.id_missing` |

Enrichment is explicit and keeps framework catch compatibility.
