Text too long · text.too_long

Stable ID: text.too_long · Evidence: source derived

The text exceeds the limit checked by this response path.

The local guard is not the public character limit for every method. Other message and caption limits can produce different descriptions.

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:

Bad Request: text is too long

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

Illustrative methods: sendMessage, editMessageText, sendPhoto.

Possible causes

• Text supplied to the formatting helper exceeds its local byte-size guard.

Before deciding what to do

Application decision: shorten text for method. Repeat request: after relevant change.

• Check the selected method’s text or caption limits and preserve valid formatting when shortening or splitting text.

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

Example

Synthetic examples derived from the cited source.

API method: sendMessage.

{
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: text is too long"
}

Python

from errorgram import classify

response = {
    "ok": False,
    "error_code": 400,
    "description": "Bad Request: text is too long",
}
result = classify(response, method='sendMessage')

assert result.id == 'text.too_long'
print(result.entry["summary"])

JavaScript and TypeScript

import { classify } from "errorgram";

const response = {
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: text is too long"
};
const result = classify(response, { method: "sendMessage" });

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