Error in Create project from backup for Standard 3D Annotation

[PWZING]

My actions before raising this issue

• Read/searched the docs
• Searched past issues
• Tested create project from backup for a 2D Annotation project succesfull

I tried to backup and restore a project for a Standard 3D annotation mode and the import of the backup failed.
I was able to export the backup without any issues.

Expected Behaviour

The project should be proberly recreated from the backup

Current Behaviour

After selecting the zipped backup and load it, an error is raised:
Could not restore the project
Error: Request failed with status code 500. "Exception: Invalid manifest was uploaded\n".

Possible Solution

Steps to Reproduce (for bugs)

1. Clone the repo and build the docker images from source from actual commit on develop branch (see commit hash bellow)
2. Create a demo project (just on label at this moment)
3. Create a new task for Standard 3D annotation with following demo sample structure (Task creation was succesfull and Pointcloud and context image are displayed correctly):
   data/
   im1/
   im.pcd
   imp.png
4. Add a single demo annotation.
5. Export Backup of the project
6. Delete the original demo project
7. Tried to import the backup to create the project again.
8. The import failed with following error message in the UI:
   Could not restore the project
   Error: Request failed with status code 500. "Exception: Invalid manifest was uploaded\n".

Context

Try to test the backup process befor starting larger projects.
