Notify uploaded file using System-assigned authentication type

Question

How can I notify the upload file using system-assigned authentication type?

I have an IoT hub using system-assigned authentication type and connected to a storage account with a private endpoint. I uploaded the file using python, and the upload was successful. If I look for the file, I can find it in the storage account. I want to notify the upload, but I got an error message related to an invalid blob name. I tried to use the same code but with a different IoT hub and different authentication type. If I use key-based authentication, I don't get that error; I only get that error if I use system-assigned authentication. I need to use the system-assigned authentication due to policies. Also, my code is in Python, and I tried using C# and I tried to make a request to the API directly and got the same message.
