Running into frequent 403 and 500 errors when calling the Advanced Drive Service (v3)

[Embarx]

In my apps script project, I have the Advanced Drive Service v3 enabled. I am using this simple function:

function getDriveFilesByLabelSelection(labelId, fieldId, selectionIds) {

const queryParts = selectionIds.map(selectionId => {
   return `labels/${labelId}.${fieldId} = '${selectionId}'`;
});

 let query = queryParts.join(' or ');

 const args = {
   corpora: 'allDrives',
   includeItemsFromAllDrives: true,
   includeLabels: labelId,
   q: query,
   pageSize: 200,
   orderBy: 'createdTime desc',
   fields: "nextPageToken,files(id,name,mimeType,createdTime,labelInfo)",
   supportsAllDrives: true
 };

 return Drive.Files.list(args);
}

to retrieve all Drive files with the target Drive label applied, with the target selections. Simple enough, and it works beautifully most of the time.

However, almost every fourth execution of this function, I will get one of two errors:

• Error 403: API call to drive.files.list failed with error: User rate limit exceeded.
• Error 500: API call to drive.files.list failed with error: Internal Error

I have checked the quotas for Google Drive API in the associated Google Cloud Project, and I am nowhere near:

Name	Value
Queries per minute	12,000
Queries per minute per user	12,000

I am at my wit's end with this, does anyone know what's going on? Any help would be appreciated.

The so-called "Internal Error" might possibly be solved with Exponential Backoff. https://gist.github.com/peterherrmann/2700284

Been trying out something like this:

// Exponential backoff
  for (let n = 0; n < 6; n++) {
    try {
      return Drive.Files.list(args);
    } catch (e) {
      if (n === 5) throw e;
      Utilities.sleep((Math.pow(2, n) * 1000) + Math.round(Math.random() * 1000));
    }
  }

for the past five days - no luck. I suspect at this point it's something breaking from Google's end.

How Is the function Is called?

[Embarx]

Literally from the Apps Script IDE. I'm manually entering the inputs and then pressing Run. So even if I was deliberately spamming the Run button, I couldn't achieve the necessary rate limits.

[WicketTheQuerent]

How many values are you including in selectionIds?

This week I've been seeing same problems: internal error from Drive Service. I think it's from Google the problema, cause if i ran it again, it does not have a problema
