bucket.move_blob not working with url encoded chars in blob name

bucket.move_blob not working with url encoded chars in blob name
getting NotFound: 404 POST https://storage.googleapis.com/storage/v1/b/[*bucket_name*]/o/test%2Fblob.csv/moveTo/o/test/blob2.csv?prettyPrint=false: Not Found

Base on the docs (https://cloud.google.com/storage/docs/copying-renaming-moving-objects#move-by-copying), the URL is not correctly encoded:
DESTINATION_OBJECT_NAME is the URL-encoded name you want to use. For example, pets/cat.png, URL-encoded as pets%2Fcat.png.

Environment details

• OS type and version: macOS Sequoia 15.6
• Python version: 3.12.9
• pip version: 24.0
• google-cloud-storage version: 3.3.0

Steps to reproduce

1. Create a blob with "/" in the name
2. try to move it with bucket.move_blob

Code example

from google.cloud import storage
gcs = storage.Client()
bucket = gcs.bucket("")
blob = bucket.get_blob("test/blob.csv")
bucket.move_blob(
    blob, 
    new_name="test/blob2.csv"
)

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!

I think the title should be "not working unless the new_name is url_encoded"? I just ran into the same case.

The Documentation for the new_name property is just this:

The new name for this blob.

nothing indicates it needs to be URL encoded (which would be surprising and likely wrong)
