@john-gom would you mind taking a look at the playwright error? It claims that the webServer exits too early - as far as I can see, all containers are up/healthy, though. Not sure if this is a know issue of some kind

Investigating...

@hangy I'm not sure what went wrong but it seemed to work OK when I refreshed the templates. Have added notes to the README on applying Keycloak updates

@john-gom Okay that makes sense. Not sure about the error message I got regarding the webServer, but that's not that important. Thank you!
