INVOICE_REPLY_DUPLICATE

A reply with this channel and external identifier already exists.


HTTP status	`409` Conflict
Retry	No

When it happens

A reply with the same channel and external_id already exists; error.details.reply_id is its id, absent when that reply was deleted. A deleted reply cannot be registered again.

How to fix it

Nothing to retry: the message is already stored, or was deleted on purpose.

Retry

Do not retry. The outcome is final: sending the same request again gets the same answer.
