Qr Code Error

I have an error trying to generate the QR Code, even though the S3 bucket is set up and working! I'm getting this error:

{
"status": 500,
"body": {
"message": "The Access Key Id you provided does not exist in our records.",
"code": "INTERNAL_SERVER_ERROR",
"data": {
"code": "INTERNAL_SERVER_ERROR",
"httpStatus": 500,
"path": "continueChat"
}
}
}
