Error: parse error: premature EOF from gs4_auth_configure()

[moldach]

From Google Cloud Platform I create credentials for OAuth 2.0 Client and it says:

Your Client ID: XXXXX
Your Client Secret: XXXXX
Download JSON

I've downloaded the JSON file and attempt to set up authorization but I get a premature EOF error

> library(googlesheets4)
> app_path <- system.file(
+     "extdata", "client_secret_581966527550-10nsh36iuvi4eoacp58tmnmsrn4m3mms.apps.googleusercontent.com.json",
+     package = "googlesheets4"
+ )
> gs4_auth_configure(path = app_path)

Your JSON file is not going to be found inside the googlesheets4 installation, which is what you're claiming above. Why are you using system.file(..., package = "googlesheets4")?

[moldach]

Same error:

> app_path <- system.file("client_secret_581966527550-10nsh36iuvi4eoacp58tmnmsrn4m3mms.apps.googleusercontent.com.json")
> gs4_auth_configure(path = app_path)
Error: parse error: premature EOF
                                       
                     (right here) ------^

[jennybc]

Why are you using system.file() at all?

[moldach]

Honestly the documentation for connecting via a server is a bit lacking and I'm struggling to make this work

[moldach]

When I type ?gs4_oauth_app() I saw the following:

# bring your own app via JSON downloaded from Google Developers Console
       # this file has the same structure as the JSON from Google
       app_path <- system.file(
         "extdata", "fake-oauth-client-id-and-secret.json",
         package = "googlesheets4"
       )
       gs4_auth_configure(path = app_path)
       

So I just tried that.

When I supply the direct path:

gs4_auth_configure(path="client_secret_581966527550-10nsh36iuvi4eoacp58tmnmsrn4m3mms.apps.googleusercontent.com.json")

How can I trouble shoot this?

[moldach]

Okay, so I created a service account on GCP then enabled API access to Google Sheets.
Next, I granted access to that e-mail account on my google spreadsheet.

Then, I create both an API Key as well as a OAuth 2.0Client ID

> google_app <- httr::oauth_app(
+   "test",
+   key = "MY-KEY.apps.googleusercontent.com",
+   secret = "MY-SECRET"
+ )
> google_key="MY-API-KEY"
> gs4_auth_configure(app = google_app, api_key = google_key)
> gs4_oauth_app()
<oauth_app> test
  key:    MY-KEY.apps.googleusercontent.com
  secret: <hidden>
>   gs4_api_key()
[1] "MY-API-KEY"

Also getting an error here?

Under the GCP Permissions I can see that my personal e-mail is set as a PRINCIPALS to this service account so I'm not sure what's wrong...

[jennybc]

You seem to be configuring 3 different auth methods (oauth user flow, API key, service account token), when I suspect you only need to want 1. It feels pretty confused.

When you get permission denied, who are you auth'ed as? Yourself or the service account?

googlesheets4::gs4_user() will reveal the user whose token is currently in force for googlesheets4.

[moldach]

Okay let's just try one method then from a fresh console. I will also create new credentials on GCP for OAuth client ID (Application Type: Desktop APP, name: test2) which allows me to download a JSON file client_secret_581966527550-qh88161edonl1hh0vj6elrpe48p72i4i.apps.googleusercontent.com.json.

If I do the following, it shows me that there is no current user?

> library(googlesheets4)
> gs4_auth_configure(path="client_secret_581966527550-qh88161edonl1hh0vj6elrpe48p72i4i.apps.googleusercontent.com.json")
> googlesheets4::gs4_user()
ℹ Not logged in as any specific Google user.

However, using gs4_oauth_app() I see:

> gs4_oauth_app()
<oauth_app> tgi-data-ingest
  key:    581966527550-qh88161edonl1hh0vj6elrpe48p72i4i.apps.googleusercontent.com
  secret: <hidden>

googlesheets4 does not load a token until one is needed. So you need to do something that requires auth or trigger auth explicitly with gs4_auth().

An OAuth app is one part of the machinery needed for a user to complete the process known as "three-legged oauth". Configuring the app does not actually obtain a token on behalf of any particular authenticated user.

[jennybc]

https://gargle.r-lib.org/articles/get-api-credentials.html#oauth-client-id-and-secret

[moldach]

trigger auth explicitly with gs4_auth().

You can not do this on Servers though....

So you need to do something that requires auth

Can you please provide code to be more clear in what I need to do?

The link you shared has those exact steps I just described for creating my OAUth Client ID above:

• From the Developers Console, in the target GCP Project, go to APIs & Services > Credentials.
• Do Create credentials > OAuth client ID.
• Select Application type “Desktop app”.
• You can capture the client ID and secret via clipboard right away.
• At any time, you can navigate to a particular client ID and click “Download JSON”.**

This was followed by me using gs4_auth_configure (which I thought you need to use if you cannot use gs4_auth?)

> gs4_auth_configure(path="client_secret_581966527550-qh88161edonl1hh0vj6elrpe48p72i4i.apps.googleusercontent.com.json")

So what step am I missing? How to I tell googlesheets4 my email address on a server?

[jennybc]

Google has shut down out-of-band auth for newly obtained OAuth apps which, presumably, includes yours. No real replacement is offered for our use case, sadly.

r-lib/gargle#202

The tidyverse oauth app which ships with googlesheets4 is grandfathered in, for a limited period of time, and can still be used for OOB auth.

So if you want to auth with a user token, via R/RStudio on a server, you have two options:

1. Use the built-in app, not your own oauth app, to get the token.
2. Create an oauth token locally (meaning: not on a server) with your oauth app and move/deploy it to the server (where it can still be used and refreshed).

The process of deploying a locally obtained token to a server is described here:

https://gargle.r-lib.org/articles/non-interactive-auth.html#arrange-for-an-oauth-token-to-be-re-discovered

[moldach]

Hi @jennybc, thanks for sharing link to option 2 there.

After creating the token locally and SCP it to the server it seems to work for the googledrive package:

> library(googledrive)
> 
> options(
+   gargle_oauth_cache = ".secrets",
+   gargle_oauth_email = TRUE
+ )
>

> drive_find(n_max = 5)
ℹ The googledrive package is using a cached token for
  [email protected].

However, I'm still getting an error from googlesheets4:

Any idea what else am I missing here?

Note: Additional issue is that I see aboveGoogleDrive is only showing 5 documents which were created by me; I do not see the document which trying to access. For this document I want to access with read_sheet my role is Editor - do you need to be the Owner?

[jennybc]

Hard to say since I'm clearly not seeing all of the code.

Or maybe I am? In which case I can say for sure that you need to explicitly tell googlesheets4 to use the same token as googledrive is using:

https://googlesheets4.tidyverse.org/articles/drive-and-sheets.html

It won't automatically do so.

[moldach]

Hi @jennybc the critical part I was missing was telling googlesheet4 to use the same token as googledrive:

> options(gargle_oauth_cache = "~/.secrets", gargle_oauth_email=TRUE)
# missing line
> gs4_auth(token = drive_token())

Thank you very much!

[NicoleRadziwill]

Giant thanks to Matthew Oldach (moldach) for asking these questions 1.75 years ago. I've been trying to deploy a Plumber API on AWS the past week, and the part I was missing was telling gs4 to use the same token as googledrive. In particular, this is how this solution worked for me (and I've tried taking out pieces of this one, so some how some way, all the pieces in this are needed):

   googledrive::drive_auth(path = "my-service-account-download-from-GCP.json") 
   googlesheets4::gs4_auth(token = drive_token())
   googlesheets4::gs4_auth(path = "my-service-account-download-from-GCP.json") 

[jennybc]

The two googlesheets4::gs4_auth() calls don't make sense to me. I would suggest lines 1 and 3:

googledrive::drive_auth(path = "my-service-account-download-from-GCP.json") 
googlesheets4::gs4_auth(path = "my-service-account-download-from-GCP.json")
