flyctl launch remove [build.args] section from fly.toml

1

This is config in fly.toml before run flyctl launch

app = "app1"

[env]
  ENV1= "test1"
  ENV2="test2"

[build.args]
  MODE="test"

[[services]]
  internal_port = 8080
  protocol = "tcp"
.
.
.

This is fly.toml after run launch which also deploy application
flyctl launch --name app1 --org org1 --region reg1 --copy-config --now

app = "app1"

[env]
  ENV1= "test1"
  ENV2="test2"

[[services]]
  internal_port = 8080
  protocol = "tcp"
  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"
.
.
.

Build argument MODE=“test” is missing and cause Docker build failure as it is defined as ARG in Dockerfile
