I followed this tutorial step by step. Only get this:
Here is my app.yml
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /
static_files: dist/fe/index.html
upload: dist/fe/index.html
- url: /
static_dir: dist/fe
skip_files:
- e2e/
- node_modules/
- src/
- ^(.*/)?\..*$
- ^(.*/)?.*\.json$
- ^(.*/)?.*\.md$
- ^(.*/)?.*\.yaml$
- ^LICENSE
I have no idea why it happens. The angular app runs on the default 4200 port. Is it the cause?
