Deployed Bot is working with emulator but not in Web Chat

One of the bots I'm working on (using Virtual Assistant Template 4.9.1.1__1) does not work if open from the "Test in Web Chat" pane in Azure. ("Sorry, it looks like something went wrong. Please try again later.")

I checked all the possible causes listed here but none of them applies to my situation. In fact the bot is working if called from the bot emulator.

Looking at

https://<bot-name>.scm.azurewebsites.net/dev/wwwroot/:output

or:

az webapp log tail -n <bot-name> -g <resource-group-name>

and nothing appears.

How can I troubleshoot what's happening?

Solution

  • I found what's causing the error: it's the embedded image size (maybe too big).

    Replacing:

    "url": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA..."

    with:

    "url": "https://myurl/myimage.jpg"

    solved the issue.

    Is there a limit on image size?
