I created a Line chatbot using Dialogflow ES (trial version).
Initially, it responded correctly based on the response I had configured. However, all of a sudden, it started falling back to the default fallback intent — even though I haven’t changed anything. (Note: I haven’t enabled webhook fulfillment.)
When checking the logs, it shows: “No matched intent” — even though the user input exactly matches the training phrase I had defined in the intent.
Additionally, I’ve already tried the following steps, but it still doesn’t work. Handling the “No matched intent” issue in Dialogflow:
-
Go to the Training menu
-
Select the “No match” conversations
-
Choose the message in question, then click to assign it to the appropriate intent
What could be causing this issue? And is there any way to fix it? Thank you for all suggestions
