In your query, I think that mimeType!='application/vnd.google-apps.folder' AND trashed=false AND 'me' in owners is correct. But about modifiedTime>='2018-11-16T14:00:00' AND modifiedTime<='2018-11-11T5:59:59', in this case, the files "after 2018-11-16T14:00:00" AND "before 2018-11-11T5:59:59" are trying to be retrieved. So the result becomes {"files": []}.
Pattern 1:
For modifiedTime, if you want to retrieve files from 2018-11-11T5:59:59 to 2018-11-16T14:00:00, how about this query?
mimeType!='application/vnd.google-apps.folder' AND trashed=false AND 'me' in owners AND modifiedTime<='2018-11-16T14:00:00' AND modifiedTime>='2018-11-11T5:59:59'
Pattern 2:
For modifiedTime, if you want to retrieve files of "before 2018-11-11T5:59:59" and "after 2018-11-16T14:00:00", how about this query?
mimeType!='application/vnd.google-apps.folder' AND trashed=false AND 'me' in owners AND (modifiedTime>='2018-11-16T14:00:00' OR modifiedTime<='2018-11-11T5:59:59')
Note:
- In your query,
2018-11-115:59:59 of modifiedTime<='2018-11-115:59:59 is wrong. But if 2018-11-115:59:59 is used, the query error occurs. So I supposes that you are using the correct value in your actual script.
