Reopen this issue.
The actual issue is that ngc hosting requires to use lowercase on models to be created.
For a model, all files it include do not have the lowercase restriction.
For example, we prepared:

https://api.ngc.nvidia.com/v2/models/nvidia/monaihosting/wholebody_ct_segmentation/versions/0.2.0/files/wholeBody_ct_segmentation_v0.2.0.zip

and wholeBody_ct_segmentation_v0.2.0.zip has the normal bundle name, but models/nvidia/monaihosting/wholebody_ct_segmentation uses lowercase.

You can also refer to the source code of uploading bundles in model zoo:
https://github.com/Project-MONAI/model-zoo/blob/de0a2f94ccb65ee5601b6c272decb059a40daee9/ci/utils.py#L188

I will create a new PR to address the issue.
