Getting a 500 error while sharing/create_shared_link_with_settings

Hi Greg-DB 

Here is the code I am using 

function generateLink_dropbox(id = "id:9TUWwcSqLjAAAAAAAAv4LA") {
let token = "";
const service = getService_();
token = service.getAccessToken();
const payload = {
"path": id,
"settings": {
"access": "viewer",
"audience": "public"
}
}
const response = UrlFetchApp.fetch('https://api.dropboxAPI.com/2/sharing/create_shared_link_with_settings', {
'method': 'POST',
'payload': JSON.stringify(payload),
'headers': {
'Authorization': 'Bearer ' + token,
'Content-Type': 'application/json',
"Dropbox-API-Select-User": "dbmid:XXXX"
},
'muteHttpExceptions': true
});
const responseCode = parseInt(response.getResponseCode());
const responseHeaders = response.getAllHeaders();
Logger.log(responseCode);
Logger.log(responseHeaders);
Logger.log(response.getContentText());
} 

Here are a few X-Dropbox-Request-Id as requested

My apps script code works otherwise. I can get folder/file details. That's where I got the id of the file from.

Now, if I manually create a link in the Dropbox UI for this particular file and re run this code, I obviously get a 409 error.

{"error_summary": "shared_link_already_exists/..", "error": {".tag": "shared_link_already_exists"}}

In that case, when I manually create a link from the UI, I can get "sharing/list_shared_links" to work, no issues there.

Funny thing though. Let's say I share this particular folder/file with my personal account. From my personal account, let's say I add it to my Dropbox (Join Folder). If I then run this code, "sharing/create_shared_link_with_settings" from my personal account, I can create links.
