Error #31 when previewing artboards

Issues
1

I just started getting an Error: Minified React error #31; visit <https://reactjs.org/docs/error-decoder.html?invariant=31&args[]=object%20with%20keys%20%7Bref%7D> for the full message or use the non-minified dev environment for full errors and additional helpful warnings. error when trying to use preview mode for some of my artboards. Example link: https://studio.plasmic.app/projects/9cwP9YqcSryDuD4dK3HDjv/preview/ewYF6KMYEtBn#width=1180&height=540

Any idea what might be the cause / how can I find it ?
(Note: I’m using custom plasmic host in this project, but I don’t have any custom components. After switching to default Plasmic host, the error is still there.)

FYI The issue lies in my TabList component. TabListItem renders correctly, but TabList not anymore

Maybe there’s a bug when one wants to place multiple elements as direct children in a slot target? Is that something not supported by Plasmic? Or just a temporary bug?

Anyways I’ve resolved the issue myself by a workaround - I changed implementation of my component so that it doesn’t use slot target, but instead a component prop that accepts an array, and I repeat the tab element by iterating over that array.

So the bug is probably still there, but it’s not a problem for me now.
