I have a page on Spark V2 that is used in a Lightning page using the Skuid:Page component. Occasionally, when navigating from standard Salesforce pages back to the detail page that contains my Skuid page I get a Lightning error related to a Theme resource. For example, I’ve seen the error after navigating away from a Submit for Approval action (standard Salesforce) back the detail page with the embedded Skuid page.
Our design system theme has just one or two style components in use - one sets a border around a wrapper. Simple things like that.
Any idea what this could be?
