error on build with gitlab pipeline

[makayabou]

Hello,
I tried to fork the project on my gitlab instance, and building ends but shows error:

java -jar third-party/SoyToJsSrcCompiler.jar --shouldProvideRequireSoyNamespaces --isUsingIjData --outputPathFormat appengine/movie/generated/en/soy.js --srcs appengine/movie/template.soy
python build-app.py movie en

third-party/build/closurebuilder.py: Scanning paths...

    raise NamespaceNotFoundError(require, source)
depstree.NamespaceNotFoundError: Namespace "soy" never provided. Required in PathSource appengine/generated/en/soy.js

goog.require('soy');
^^^^^^^^^^^^^^^^^^^

appengine/generated/en/soy.js:11: ERROR - required "soydata" namespace never provided
goog.require('soydata');
^^^^^^^^^^^^^^^^^^^^^^^

when I go to the page (https://garagenum.gitlab.io/blockly/appengine/index.html) , I can look at source page and go to css and js links, but nothing is showed.
Locally it works well..
I really don't know what the problem is, maybe something about path because basepath for server in my gitlab instance is /blockly ...

Thanks for your help
