Hi @arch, Our visualizations plugin infrastructure has been going through a lot of churn since `7.5` -- I have posted a more detailed explanation [in this Github issue](https://github.com/elastic/kibana/issues/52511#issuecomment-597336887), but the TLDR is that we recommend waiting to upgrade custom plugins until after `7.7`. In the meantime, you might be interested in checking out this thread from another user who is building a custom plugin in `7.6`: [Kibana 7.6: set uiState doesn't seems to work](https://discuss.elastic.co/t/kibana-7-6-set-uistate-doesnt-seems-to-work/219844/2) Specifically they point to [some example code they put up on Github](https://github.com/pchakour/kibanaUiStateIssues) which uses a custom request/response handler. (Worth noting that they are using Angular, not React -- I would strongly recommend sticking with React but hopefully that post is still informative). Hope this helps a bit! We are expecting to have a much more useful (and documented!) API for custom visualizations coming soon in `7.x` Luke --- _[View the full topic](https://discuss.elastic.co/t/request-response-handlers-in-visualizations/221727)._
