Still the error seems to suggest at least some part in the path of /home/runner/work/MyApp/MyApp/_build/test/lib/my_app/priv/static/uploads/ebeab0e5-115e-4ace-a6a7-776877c325f4.png does not exist. You might have mantually created the uploads directory in development, but in CI it’s not present.

Not sure why it’s not there… When I check _build/test/ on my local machine, lib/my_app/priv/static/uploads is there alright, and I know I didn’t create that manually. If it’s missing, how can I ensure the folder is being created in the build?

In the :dev and :test environments, the priv dir is a symlink to the /priv dir at the root of your app.
/priv/static/ is included in the .gitignore for a Phoenix app by default, so if I had to guess your priv directory likely exists in prod, but the sub-directories do not.
Somewhere in your production build you can run mkdir -p /path/to/my/app/priv/static/uploads to ensure the directory exists.
PS– With the latest release of LiveView we updated the Uploads guides to use :code.priv_dir(:my_app) when building the path (though I probably would have used Application.app_dir if I had thought about it at the time).

Thank you! I simply added a step in the CI workflow to run mkdir before running the test. Now the test is successful.
