Hi guys I can’t seem to fix this.
I’ve search this forum and google and couldn’t find the answer.
Thanks for your time.
Here’s the full error:

One thing I notice is that it didn’t add telemetry, phoenix live, etc… The phoenix live salt isn’t added in the config either during the upgrade process.
When I create a new project the mix file doesn’t include {:phoenix_pubsub, "~> 2.0"} where as all the upgrade tutorials (chris’s git and this one ) instruct to add it in your mix file.
Do note that I’m using {:plug_cowboy, "~> 2.2"}, for some compatibility reasons…
