This looks like it might be caused by a plugin without a description, but there aren’t any such plugins in the marketplace – from the developer console that @XxLilBoPeepsxX kindly demoed, can you capture and share the response payload of the API request to /api/v4/plugins/marketplace? Note that this will include local plugins that aren’t actually in the marketplace, so be sure to sanitize anything if you don’t want to share it here.
