Additional context

It happens only with Directline webchat , if you test through emulator it works fine

Thanks for reporting this issue @aparnaji .

This is a known issue with Web Chat. Emulator manages the locale so that's why the expected behavior is observed when using Emulator, however the Direct Line channel does not know the locale at the time of initializing the conversation and sending the conversation update to the bot.

As a workaround, you can try implementing a custom welcome message event as demonstrated in this sample:

@stevkan can you please keep an eye on this?

Thanks for update, Issue that I have is only the greeting dialog has this issue subsequent dialogues are coming in right locale. I tried with the code that u shared and I am having the same issue

@aparnaji, test if this option works for you. In my own testing, it works. FYI, this assumes you have implemented the custom welcome message event referenced above in the 'a.welcome.event' sample.

1. In the Greeting trigger (ConversationUpdate activity), remove or disable all actions within it
2. Add an Event received trigger (Event activity)
3. In the event trigger:
   a. Click add an action
   b. Select Create a condition
   c. Choose 'Branch: If/else'
   d. In the Condition field, enter turn.activity.name == "webchat/join"
4. Under True of the 'Branch: If/else':
   a. Click add an action
   b. Select Create a condition
   c. Choose 'Branch: Switch (multiple options)'
   d. In the Condition field, enter turn.activity.locale
5. Under Cases, add a Value for 'hi-IN' and 'en-US'
6. For each case, add the action(s) you want to have happen there (i.e. the type of greetings you want displayed)

At this point, when Web Chat establishes a connection to Direct Line, the bot will still receive the conversationUpdate. Since the code contained within that trigger was disabled/removed, the bot will essentially skip it.

Once the connection to Direct Line has completed, Web Chat will fire off an event activity with the name value of webchat/join and a value of window.navigator.language. Note: the 'a.welcome-event' sample sends an event with a payload value of { window.navigator.language }. I chose NOT to send it as an object and, instead, just sent the string.

The bot, looking for a specific event that has the locale defined in the value property, will filter on the locale displaying the appropriate greeting message, as a result.

Closing as resolved.
