Hello omeersari,

The platform does not directly handle Git submodule authentication during the standard deployment process.

To deploy a project with private Git submodules, you will need to use a Dockerfile approach.

Please note that while we can confirm this is the required approach, we are unable to provide specific guidance on creating or configuring your Dockerfile, as this falls outside the scope of what we can offer support for, and it would be very specific to your project.
