The community member is experiencing an issue where a background image set using a variable {{bg}} is not being displayed, even though the same image URL works when manually entered. The community members suspect a bug where the variable is not being executed, and its value is not being returned. Other community members confirm this is a bug and that it is being fixed soon. A link to the issue on GitHub is provided.
I uploaded my desired bot background on Imgur. When I fill the image URL manually in the Theme's Global tab Background "URL", the background is properly displayed. However, when I use my defined variable {{bg}}, which I define as the very first block of the flow with the same exact image URL, and use {{bg}} in the Background "URL" field, it doesn't display it. As you can see, the browser CSS thinks the actual background-image is the raw variable call.
I suspect a bug where the variable is not executed, therefore its value is never returned
