For example, if I try to hit the auth
endpoint with the wrong password, I will get a 400 Bad Request with response object including the following properties, which I would like to show in the front-end application UI:
key: "error.user.password.notSame"
message: "The passwords do not match"
Are these messages translated in most common languages, e.g. French, German, Spanish etc. and available automatically e.g. via a URL param?
If not, is there a best place for me to add these translations? e.g. language variables? Can I find an index of these messages so I can make sure we translate all of them?
