Describe the bug

I tried to add a Markdown formatted string into my Bot solution. From Bot I send simple text "See you later!" using
await context.sendActivity(See you later!)
Emulator works fine and formatted text is rendered correctly.
But my ReactWebChat client doesn't work. No formatted text is displayed. You can see received message text in console (screenshot).
No additional code related to markdown formatting is used currently (no 'textFormat' at the Bot's side, no Markdown renderer at WebChat side)

Steps to reproduce

1. Open the Bot's client
2. Type something to get formatted message from Bot
3. See not formatted text in UI, and correct text value in console

Expected behavior

1. Open the Bot's client
2. Type something to get formatted message from Bot
3. See formatted text in UI (like in Emulator), and correct text value in console

@vojtechkacmarik, I am unable to repro the issue. I do see that it appears you are using Direct Line to post activities which may be the problem (#3634). Using DL in this way isn't necessarily bad, however, DL is already baked into Web Chat with a variety of methods built around it to support and extend its functionality. Using DL on top of Web Chat could somehow be causing interference.

Rather than use DL, the recommended method is to use Web Chat's store to generate activities sent back to the bot. For example, reference the 04.api/a.welcome-event sample. There are many other samples available that demonstrate the different ways the store, middleware, and other features can be utilized.

Can you please try restructuring and try again to see if this mitigates the problem?

[vojtechkacmarik]

Thank you for response. I checked current behavior of DL related to MemberAdded and this activity (conversationUpdate) is sent correctly to Bot (I'm using token with userID). So I completely removed code posting activity webchat/join using DL.
Unfortunatelly the behavior is the same.
Although welcome text is received at Client side no message displayed and rendering error 'Cannot read property 'decodeEntities' of undefined' occurred in console. Valid only when UI is rendered for firts time, other render is correct.
No Store implemented yet.

Markdown still not rendered

@vojtechkacmarik, thank you for your patience. Are you able to include all of your Web Chat code so I can look it over? Also, the code that is responsible for receiving the response and is generating the error, bot-side?
