Expected behavior

My project has Webpack, React and Tailwind. Making a flatpak, whether via Github Action or on the host machine causes the same issue:

✖ Making a flatpak distributable for linux/x64 [FAILED: flatpak failed with status code 1]
✖ Making distributables [FAILED: flatpak failed with status code 1]

An unhandled rejection has occurred inside Forge:
Error: flatpak failed with status code 1

Any possible causes? Thanks
