InvalidCredsError with upload_object_via_stream() on Aurora Objects

[WBNet-Wout]

Summary

When trying to upload a file to Aurora Objects through upload_object_via_stream(), I get an InvalidCredsError.

Detailed Information

When I try the following code:

from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver

cls = get_driver(Provider.AURORAOBJECTS)
driver = cls('api-key', 'secret-key')

container = driver.get_container('container')

container.upload_object_via_stream(iter([b'test']), 'test.txt')

It results in the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/wout/project/.venv/lib/python3.9/site-packages/libcloud/storage/base.py", line 216, in upload_object_via_stream

    response = responseCls(**kwargs)

    raise InvalidCredsError(self.body)
libcloud.common.types.InvalidCredsError: '<?xml version="1.0" encoding="UTF-8"?><Error><Code>SignatureDoesNotMatch</Code><RequestId>tx00000000000004e0ebfe5-00620a68e9-1d4a885a-ams02</RequestId><HostId>1d4a885a-ams02-eu</HostId></Error>'

However upload_object() is working fine as follows:

from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver

cls = get_driver(Provider.AURORAOBJECTS)
driver = cls('api-key', 'secret-key')

container = driver.get_container('container')

container.upload_object('test.txt', 'test.txt')

I am using Python 3.9.8-1 on Debian unstable with Libcloud 3.4.1.
