No objects returns when delimeter = "/" is set

[erydit]

Hello!

I am working with the public Sentinel-2 bucket ( https://console.cloud.google.com/storage/browser/gcp-public-data-sentinel-2 , https://console.cloud.google.com/marketplace/product/esa-public-data/sentinel2?project=rivcmonitor ).

and before the last update the following code was working:

library(googleCloudStorageR)

gcs_auth(json_file = gcs_json)
gcs_sentinel2_bucket <- gcs_get_bucket(bucket = "gcp-public-data-sentinel-2")

entries <- gcs_list_objects(
        bucket = "gcp-public-data-sentinel-2",
        detail = "more",
        prefix = "L2/tiles/38/U/PF/",
        delimiter = "/",
        versions = FALSE)

That code successfully return a data frame with all folders of sentinel2 scenes (https://console.cloud.google.com/storage/browser/gcp-public-data-sentinel-2/L2/tiles/38/U/PF)
Now it returns an error:

Warning

ℹ 2026-03-13 17:04:06.331419 > No objects found
Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 0, 1

However, the code without delimiter works as expected:

entries <- gcs_list_objects(
        bucket = "gcp-public-data-sentinel-2",
        detail = "more",
        prefix = "L2/tiles/38/U/PF/",
        delimiter = NULL,
        versions = FALSE)

head(entries, 3)

returns:

Which version were you running before and now? The latest GitHub version?

Which version were you running before and now? The latest GitHub version?

I am really dont sure. The last time I was using the googleCloudStorageR to find and download sentinel data from public storage was the end of the past year.

Now the CRAN version is installed, and it was built 2026-03-13 :

Maybe some changes were made to the Google Storage itself? I didn`t noticed any changes.

[erydit]

Am I doing something wrong?
