Thanks for confirming!
I’m afraid this one happens when you try to set a background style, so it is the page setting problem rather than plugin related. It is entering an infinite loop which creates the circular reference, unfortunately, which is not allowed in Bubble.
There is a possible workaround where you can use something else, like a new state, dependent on the plugin element ‘upload progress’ to set the plugin element background.
Of course, this solution is not perfect, first because making the page to poll every second for plugin state is not performance friendly, second because it’s still not instantaneous.
However, we’ll try to improve the plugin in some upcoming future so perhaps it doesn’t create the circular reference and the background style can be used with no errors. If you like our plugin so far, could you please rate it by going to Plugins tab in Bubble editor? You can find the plugin by name and give it as many stars as it deserves. The more feedback we get, the more motivated we are to build great plugins.
