Unable to pull ad account data

Hello,

I'm trying to pull ad account data into R, but it keeps either failing or timing out. This could be to do with an API issue (as I know Facebook are having some problems at the moment), but I'm not convinced because the error message says:

Error in fbad_request(path = url$path, method = "GET", params = url$params, :
Unsupported get request. Object with ID 'vhttps:' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api

Anonymised code below

fb_token <- "my_token"
Account <- fbad_init(accountid = "my_account", fb_token, version="10.0")

FB_raw <- fb_insights(level="ad",time_increment=1,date_preset="this_year",breakdowns="publisher_platform",
                      action_attribution_windows="28d_click,7d_view",
                      fields=toJSON(c("campaign_name","adset_name","ad_name","spend","impressions",
                                      "inline_link_clicks","actions","converted_product_value"))) %>%  do.call(rbind.data.frame,.)

This used to work fine with API v9.0, but today is the first time I've used it since that was deprecated - so wondering if it's version 10 that's actually causing the issue. Any help much appreciated.

Many thanks,

Jeremy
