45207: Chat User per Chat Channel limit reached. User is part of too many Chat Channels.

This error occurs when a user has reached the maximum number of Chat Channels they can belong to at the same time. In Flex, this usually means an agent was not removed from older or inactive Chat Channels after work on a task finished.

• The user is still a member of too many active or inactive Chat Channels.
• Flex orchestration did not remove the agent from the Chat Channel after the related task was completed.
• A custom task channel or custom Flex implementation is not correctly configured to handle chat channel membership.
• Custom code is adding users to channels without removing them when the conversation is finished.
• The configured Chat Channel membership limit is too low for your current workflow.

• Review the user's existing Chat Channel memberships and remove them from inactive channels that are no longer needed.
• Check your Flex workflow and task lifecycle to confirm agents are removed from Chat Channels when work is complete.
• Review any custom Flex UI or backend logic that manages chat-capable task channels and channel membership.
• If you manage channels directly, use the Programmable Chat API to remove members from channels that should no longer be associated with the user.
• If your use case requires a higher limit, review your Chat Channel limit settings in Console and adjust them if appropriate.
• If the issue happens repeatedly, audit your implementation for channels that remain open or tasks that never complete properly.
