Dify version

1.9.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

create a chatflow
start the conversation

for the collection of things that you changed and didn't notice users about the breaking change here's another one:

dialog counter starts from 1 instead of 0 like it was up to version 1.8.1

✔️ Expected Behavior

The dialog count should have remained the same as in version 1.8.1 because there might be chatflows that rely on the dialog counter to detect if a chat is ongoing or just starting

Actual Behavior

the counter in 1.8.1 was set to start from 0

Image

the counter in 1.9.1 starts from 1
