    "PreUploadUrl":"https://xxx.s3.us-west-1.amazonaws.com/xxx/3706/627855d5-ba01-4732-9dfd-b08a72744c77.txt?X-Amz-Expires=600\u0026X-Amz-Algorithm=AWS4-HMAC-SHA256\u0026X-Amz-Credential=AKIA5TS7CBKE4ZSWBI46%2F20250121%2Fus-west-1%2Fs3%2Faws4_request\u0026X-Amz-Date=20250121T030214Z\u0026X-Amz-SignedHeaders=host\u0026X-Amz-Signature=a237335d9b2e6fad1c648f753d393906647db5528eaaecf5e55dd114a22653db",
  },
  "Version": "1.0.0",
  "Success": true,
  "Code": 200,
  "Message":""
}

Error Handling​ #

If it’s an HTTP network error, you should check the HTTP status code. If it’s a business exception, you need to examine the Code and Message fields, which will provide the error details.

That’s it! You should now be able to create a chatbot using the create API.
