Errorgram

Member is administrator · member.is_administrator

Stable ID: member.is_administrator · Evidence: source derived

The operation was rejected because the target user is a chat administrator.

The mapping does not identify the user’s exact administrative role or authorize changing it.

When it matches

Section titled “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: user is an administrator of the chat

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

Illustrative methods: banChatMember, restrictChatMember.

Possible causes

Section titled “Possible causes”
  • The requested action targets a chat administrator.

Before deciding what to do

Section titled “Before deciding what to do”

Application decision: review target member role. Repeat request: after relevant change.

  • Confirm the intended user and current role; any necessary role change must follow the chat’s authorization policy.

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