Integration Test Failure: get Command on Non-Existing Object

Description

There is an integration test that is currently failing when attempting to get a non-existing object. The test expects the CLI to return an error, but it does not. Instead, the command completes without raising an error.

Steps to Reproduce

Run the integration tests or the following command:

go run . -c config.json get "non-existent-file" /dev/null
echo $?

Observe that the command does not return an error, even though the file does not exist.

Expected Behavior

The CLI should return an error when attempting to get a non-existing object. Specifically, the implementation should raise an error when the downloaded file size is 0.

Actual Behavior

The CLI completes the command without raising an error, even when the file does not exist.

Suggested Fix

Adapt the implementation to raise an error when the downloaded file size is 0. This behavior is already correctly described by the current test.
