Flatpak-builder cannot find git source files

Hi, my manifest file is as follows:

In the git source I mentioned, there is a Cargo.toml, deptree.json and a resources folder. I want flatpak-builder to build my project with the content of these folders and files.

However I realized flatpak builder can’t recognize my deptree.json file and can’t access anything fetched from the upstream git repo.

Where is the git-fetched repos downloaded. I tried /run/build/$module but it didn’t work.

I fixed it by hard-cloning my original repo.

Edit: Turns out, I needed to manually add the generated dependency file in the flathub repo.
