Dify version

1.6.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

1. Create a Dify Chatbot
2. Integrate this Chatbot into Typebot (self-hosted)
3. Chat with the chatbot
4. Attempt to delete the chat using the REST API command as provided in the documentation:
   curl -X DELETE '${SERVICE_API_URL:-https://dify-u46470.vm.elestio.app/v1/conversations/:conversation_id'
   --header 'Authorization: Bearer {api_key}'
   --header 'Content-Type: application/json'
   --data-raw '{
   "user": "abc-123"
   }'

✔️ Expected Behavior

I am expecting the documented response: 204 No Content

❌ Actual Behavior

Instead, I am getting this error:
{
"errorMessage": "The resource you are requesting could not be found",
"errorDescription": "Conversation Not Exists.",
"errorDetails": {
"rawErrorMessage": [
"404 - "{\"code\": \"not_found\", \"message\": \"Conversation Not Exists.\", \"status\": 404}\n""
],
"httpCode": "404"
},
"n8nDetails": {
"nodeName": "Delete Conversation",
"nodeType": "n8n-nodes-base.httpRequest",
"nodeVersion": 4.2,
"itemIndex": 0,
"time": "23.7.2025, 19:00:58",
"n8nVersion": "1.102.4 (Self Hosted)",
"binaryDataMode": "default",
"stackTrace": [...]
}
}

However, the converstation does exist (see screenshot) and (I am very much assuming), was created via API integration if I am using Typebot, thus should be deletable via API too.
