Hello team,
A few days ago I had several issues related to the API Request usage limit (it had exceeded 3000). After adjusting some settings, the usage counter reset normally.
However, now I’m facing a different problem.
When I try to fetch older messages from a conversation using n8n and the Dify API endpoint /v1/chat-messages, I consistently receive the following error:
The resource you are requesting could not be found.
Conversation Not Exists. You have requested this URI [/v1/chat-messages]
but did you mean /v1/chat-messages or /api/chat-messages or /v1/chat-messages//stop ?
The strange part is:
-
The conversation ID absolutely exists inside Dify.
-
When I search for the same conversation directly in the Dify dashboard, it appears normally.
In the dashboard I can open the conversation and see the whole history, but the API returns “Conversation Not Exists”.
This issue started happening only after the API usage counter reset.
Could you please help me understand why the API can no longer access old conversation messages, even though they still exist inside Dify?
Thank you!
