Fix gcs_copy_object() to use bucketLevel permissions

[MarkEdmondson1234]

@MarkEdmondson1234 Thanks for the Hotfix. But i Think you missed the gcs_copy_object() function. There should also be a parametervalue "bucketLevel". I tried it with the latest github commit, but it didn't work. and it says

Request Status Code: 400 Error: API returned: Invalid string value: 'bucketLevel'. Allowed values: [authenticatedread, bucketownerfullcontrol, bucketownerread, private, projectprivate, publicread]

As long as the update isn't available in CRAN. Can you please post a snippet which removes the ACLs from the call to get this work?

@Pit-Storm best tracked in a new issue

It will involve adding a blank ACL object as shown in this commit https://github.com/cloudyr/googleCloudStorageR/commit/37f922cc5ce96a3bfdbcdc4f6c0466991ebe18bc to the gcs_copy_object() code:

@Pit-Storm what example code are you using to trigger your error? From the looks of it not specifying the ACL should respect that existing objects ACL level.

I fixed it by setting predefinedACL to NULL.

Aren't you think that this is little inconvenient with respect to the upload function?

I'm a bit confused as the default is NULL. May I ask for the example code you used and the sessionInfo(), it could be that its just fixed on GitHub?

[Pit-Storm]

I think I made some missunderstandable comments.

In the first place, I used predefinedACL="bucketLevel" because I knew the setting from the upload object. I wasn't trying without the predefinedACL parameter. After it didn't work, I checked the docs for it. There wasn't any bucketLevel or NULL setting for this parameter mentioned. For this reason i opend the ticket. After that, I saw that there had been a discussion on that and your suggestion to set the ACL to NULL when doing the call. So I tried predefinedACL=NULL. I didn't check the dfault setting.

As far as I can see that issue it is a peace about docs and a peace about convenient parameter settings. In my eyes it is a little confusing why one has to be set the predefinedACL on the upload function explicitly if the bucketLevelACLs are enabled and on the other side one is able to use a default parameter setting with the copy function. But I'm not sure if I missunderstood something in general.

Kind regards

PS: I'm not able to provide a full working code example for now, because I'm not at my work machine.

Makes sense, yes it can be changed to be more consistent.
