Aqueduct server quits working after upgrading to 4.0.0

Question

I upgraded Dart to 2.8.4 and Aqueduct to 4.0.0-b1.

On the linux server I was starting the server with a daemon like this:

[Unit]
Description=My server

[Service]
User=web
WorkingDirectory=/home/web/dart/my_server
ExecStart=/home/web/.pub-cache/bin/aqueduct serve
Restart=always

[Install]
WantedBy=multi-user.target

But Aqueduct won't start now.

Answer 1

Use pub run to start Aqueduct now:

pub run aqueduct serve

In version 4.0.0 the Aqueduct server is AOT compiled. (I'm not sure yet why that means you have to use pub run, though.)

Your daemon file should be changed to this (depending on the location of pub on your system):

ExecStart=/usr/lib/dart/bin/pub run aqueduct serve
