4.11.0 minimal bundle => No renderer for attachment for screen reader of type XY

Screenshots

Version

4.11.0 / NPM (‘botframework-webchat/lib/index-minimal’) / (but it also happening using CDN minimal bundle)

Describe the bug

We’re using the minimal bundle for our webchat. We’re rendering all of the messages by our self. Since we’ve updated to 4.11.0, all activities are still rendered as before, but there are errors in the console about missing renderers for screen readers, like:

ErrorBox.js?ffa8:44 Error: No renderer for attachment for screen reader of type "application/vnd.microsoft.card.hero"

Steps to reproduce

1. Run this sample 01.getting-started/b.minimal-bundle
2. Open console in developer tools
3. Type “help”
4. Observe errors

Expected behavior

I expect to have one of the following:

• renderers in that bundle
• no renderers but no errors
• documented a way how to suppress/ignore errors from missing renderers => any idea to work around the issue?

Hi @martinoss, thanks for filing this issue. I have a repro of this, and will investigate the problem. I don’t think I’ll get an answer to this thread today, but I will get it in as soon as possible early next week.

1. change to warning, not error
2. suppress warning? React props.ref - console log ==> warning, align with this behavior / production
   1. npm build - production vs start (dev)
   2. if suppressable, write sample
   3. default props (not style options)
   4. suppress red box in production & no announcement in screenreader (when WC dep in CRA)
3. Sample for suppressing warnings (from test code)
4. dev mode, non-suppressed - have screenreader renderer saying activity could not be rendered
