When I try to deploy, the deployment stops at phase assets compilation:

-----> Compiling assets

A remote command failed on:

  deploy@x.x.x.x

Output of the command is shown above and the command executed
on that host is printed below for debugging purposes:

FAILED with exit status 2:

       [ -f ~/.profile ] && source ~/.profile
       set -e
       cd '/tmp/edeliver/myapp/builds'/assets
       node_modules/.bin/webpack --mode production --silent

but there is not error details about it, how can diagnose the error?
I tried to ssh into the server, and run the command above node_modules/.bin/webpack --mode production --silent in assets directory, but it passed without error…
