Description

Needs: Attention :wave: type:bug
Describe the bug

I am trying to upload a .docx file into OneDrive using Graph API. Unfortunately, it returns an error 400.

msgraph.generated.models.o_data_errors.o_data_error.ODataError:
{
APIError
Code: 400
error: MainError(code='BadRequest', message='Entity only allows writes with JSON Content-Type header.')
}
Expected behavior

Based on the type from the code of the sdk passed type is correct, so I don't understand this behaviour and the bellow code should upload the file.

How to reproduce
file_path = "test.docx"
with open(file_path, "rb") as file_handle:
    file_bytes = file_handle.read()

item_path = "/root:/Documents/test_on_one_drive.docx"
r = await client.drives.by_drive_id(drive_id).items.by_drive_item_id(item_path).content.put(body=file_bytes)
SDK Version
