Non-interactive auto-refresh stale OAuth Token with Googlesheets package - launchd

Question

I'm trying to automatically run an r script to download a private Google Sheet every hour. It always works fine when I'm interactively using R. It also works fine during the first hour after I automate the script with launchd.
It stops working an hour after I start automating it with launchd. I think the problem is that after one hour the access token changes, and the non-interactive version isn’t waiting for the auto refreshing of the OAuth token. Here is the error that I get from the error report:
Auto-refreshing stale OAuth token.
Error in gzfile(file, mode) : cannot open the connection
Calls: gs_auth ... -> -> cache_token -> saveRDS -> gzfile
In addition: Warning message:
In gzfile(file, mode) :
cannot open compressed file '.httr-oauth', probable reason 'Permission denied'
Execution halted
I'm using Jenny Bryan's googlesheets package. Here is the code that I initially use to register the sheet, and then save the oAuth token:
gToken <- gs_auth() # Run this the first time to get the oAuth information
saveRDS(gToken, "/Users/…/gToken.rds") # Save the oAuth information for non-interactive use
I then use the following script in the file that I automate with launchd:
gs_auth(token = "/Users/…/gToken.rds")
How can I avoid this error when running the script automatically with launchd?

I don't know about launchd but I had the same problem when I wanted to run a R script automatically from the Windows task planer. Changing the 'cache' attribute value to FALSE did the trick for me [1]: https://i.stack.imgur.com/pprlC.png
You can find the solution here: https://github.com/jennybc/googlesheets/issues/262
To authenticate once in the browser in order to get a token file, I did this:
token_file <- gs_auth(new_user = TRUE, cache = FALSE)
saveRDS(token_file, "googlesheets_token.rds")
Automatic login afterwards via:
gs_auth(token = paste0(path_scripts, "googlesheets_token.rds"),
verbose = TRUE, cache = FALSE)
