Nicola Crane commented on ARROW-17894:
--------------------------------------
Thanks for reporting this [~cboettig] and for adding a potential solution there
[~joran_elias]! If this works for you [~cboettig], do you fancy submitting a
PR to update those docs?
> [R] Documentation for json_credentials is misleading
> ----------------------------------------------------
>
> Key: ARROW-17894
> URL: https://issues.apache.org/jira/browse/ARROW-17894
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Affects Versions: 9.0.1
> Reporter: Joran Elias
> Priority: Major
> Fix For: 11.0.0
>
>
> For authenticating with GCS via a JSON credentials file, the documentation
> under ?FileSystem for GcsFileSystem$create() says:
>
> * {{{}json_credentials{}}}: optional string for authentication. Point to a
> JSON credentials file downloaded from GCS.
>
> Additionally, the GCS Authentication section of Working with Cloud Storage
> (S3, GCS) in the file system vignette says:
> {quote}or {{{}json_credentials{}}}, to reference a downloaded credentials
> file.
> {quote}
>
> Both of these seem to imply that json_credentials expects a path to a JSON
> credentials file downloaded from GCP. However, when a file path is provided
> you get an invalid argument error:
>
> {code:java}
> > bucket <- gs_bucket(bucket = 'pinned_data',json_credentials = json_path)
> > bucket$ls(recursive = TRUE)
> Error: Invalid: google::cloud::Status(INVALID_ARGUMENT: Permanent error in
> ListObjects: Invalid ServiceAccountCredentials,parsing failed on data loaded
> from memory). Detail: [errno 22] Invalid argument
> {code}
>
> However, if you pass a string containing the raw JSON from the file itself,
> the above code snippet works and returns the names of the objects in the
> bucket.
> Both sections of the documentation should be clarified to explicitly say that
> the argument expects the actual JSON rather than a file path to the JSON file.
