Cloudflare email worker

Hello
I’m getting delivery failed in some forwarded email, when i used logs to see the real problem i got this message

{
“outcome”: “exception”,
“scriptName”: “dido”,
“diagnosticsChannelEvents”: ,
“exceptions”: [
{
“name”: “Error”,
“message”: “message already forwarded to this destination”,
“timestamp”: 1701084117580
}
],
“logs”: ,
“eventTimestamp”: 1701084087115,
“event”: {
“rawSize”: 7688,

so why i’m getting “message already forwarded to this destination” only in some emails (not addresses) ?
