Server restarting · server.restarting

Stable ID: server.restarting · Evidence: source derived

The bot client is closing for a server restart.

An exception wrapper that discarded the original 5xx description cannot recover this distinction from the status alone.

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: 500.

Exact description:

Internal Server Error: restart

See matching rules for parameter precedence and unknown or ambiguous results.

Possible causes

• The bot client is closing without taking the logout branches.

Before deciding what to do

Application decision: backoff and reassess operation. Repeat request: policy dependent.

• Apply bounded backoff and evaluate whether repeating the particular operation is safe; do not derive replay safety from a 5xx status alone.

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: getMe.

{
  "ok": false,
  "error_code": 500,
  "description": "Internal Server Error: restart"
}

Python

from errorgram import classify

response = {
    "ok": False,
    "error_code": 500,
    "description": "Internal Server Error: restart",
}
result = classify(response, method='getMe')

assert result.id == 'server.restarting'
print(result.entry["summary"])

JavaScript and TypeScript

import { classify } from "errorgram";

const response = {
  "ok": false,
  "error_code": 500,
  "description": "Internal Server Error: restart"
};
const result = classify(response, { method: "getMe" });

if (result.status === "matched" && result.id === "server.restarting") {
  console.log(result.entry.summary);
}

Framework names

Integration	Type or ID
