Cannot read property 'role' of undefined

I used chatdown v1.0.9-20 to convert a very simple .chat file into a .transcript file.

I got the following error when I open the .transcript file in Bot Framework Emulator (4.0.0-preview.40025) Error creating a new conversation in transcript mode: Error: Error while feeding transcript on disk to conversation: Cannot read property ‘role’ of undefined

I don’t know if it’s related to chatdown or Bot Framework Emulator.

Here the .chat file:

user=vishwac
bot=cafebot

user: hi
bot: Hello, I'm the contoso cafe bot. How can I help you?

Here the .transcript file generated by chatdown:

This is a known issue with chatdown. Updating to 1.0.10 fixes this problem. As a workaround, the emulator uses this version under the hood and can convert .chat files into transcripts and feed them into the chat window automatically. To do this:

1. open a bot file in the emulator
2. click on the resources icon
3. Click on the cogwheel to open the settings dialog and browse to the location of the directory that your chat files are in.
4. Click “Save Changes”
5. you should now see your chat files in the scripts pane. Clicking on the chat will convert it to a transcript and display it in the chat window

@paulfitz72 I was unable to reproduce this with botframework-cli@4.5.4 and both version 4.5.2 of the Emulator, and the newest nightly build.

user=Tony
bot=MrBot

user: Hey bot!
bot: Hello Tony!
