Freshly installed desktop client on os x 10.15.7 via homebrew.
Reproduction
brew tap hashicorp/tap && brew install hashicorp/tap/boundary
brew install hashicorp-boundary-desktop
boundary dev
- open Boundary application
- provide localhost endpoint to application
- error displayed on following screen
Updates
I replaced the brew installed version of the desktop client with a copy via direct download and noticed that the app A.) automatically used http://localhost:9200
as the endpoint and B.) didn’t have any en-us locale/translation issues.
