45208: Chat Channel with this unique name already exists

Twilio could not create the Chat Channel because another active Chat Channel already uses the same unique name. Unique channel names must be distinct among active channels.

• You attempted to create a new Chat Channel with a UniqueName value that is already assigned to an active channel.
• Your application retried channel creation with the same UniqueName after the first channel was already created.
• A previous channel with that unique name still exists and has not been marked inactive or removed.

• Use the existing active Chat Channel instead of creating a new one.
• Update your application logic to generate a different UniqueName for each new channel you create.
• If you no longer need the existing channel, mark the channel as inactive by updating the channel attributes to set status to inactive.
• Remove the existing Chat Channel if it is no longer needed, then create a new channel with that unique name.
• Check for an existing channel before you create a new one so your application does not submit duplicate channel creation requests.
