I am trying to deploy the app with edeliver. However during the … I get the following error. Not sure what is it actually means. Though in the dev environment it works fine.

1. mix compile - Successful
2. iex -S mix phx.server - I can serve the api and no issues.
3. Guardian can also authenticate the JWT token

So puzzled about deployment.

Building the code for edeliver

mix edeliver build release --verbose

Error:
