Hey @User > Also where is the location of the config file that you can edit? The config.yaml file in the docker container is located at /usr/lib/supertokens/config.yaml > My licensekey says 'production'? i start my docker instance in 'dev' what does this mean? Starting the docker image in dev mode means that you want to use it for development. This is independent to do with the licenseKey being in production. The difference between starting supertokens in dev or production mode is explained here: https://supertokens.io/docs/community/cli/start#starting-in-a-development-environment > I keep getting this error: Did you fix this error? I saw you had opened an issue on github about this, but it's not there anymore. Let me know. > I think I need to migrate from 1.0 to 2.0 what do i need to change? You should not need to change any of the nodeJS code for this.
