[Python V2] How to do batch upload?

Greg-DB  - Thank you for following this and providing input. I think I'm close to a solution and will continue tinkering. In the meantime, please review my method below and provide any further suggestions.

For output, I am getting an "UploadSessionFinishBatchLaunch" return at the end with an async_job_id. However, nothing is uploaded to dropbox after completion. Thank you.

from os import listdir
from os.path import isfile, join
import dropbox

def batchUpload(srcFiles, dstDir, dbx=None):
    if not dbx: dbx = DropboxTeam(DROPBOX_TOKEN).as_admin(ADMIN_ID)
    chunkSize = 2 * 1024 * 1024
    uploadEntryList = []
    for src in srcFiles:
        
        baseName = os.path.basename(src)
        dstPath  = dstDir + "/" + baseName
        fileSize = os.path.getsize(src)

        print("{0} ==> {1}".format(src, dstPath))

        with open(src, "rb") as fp:
            if fileSize <= chunkSize: # file smaller than chunkSize, no files_upload_session_append_v2
                uploadSessionStartResult = dbx.files_upload_session_start(fp.read(), dstPath, close=True)
                cursor = dropbox.files.UploadSessionCursor(session_id=uploadSessionStartResult.session_id,
                                            offset=fp.tell())
                commit = dropbox.files.CommitInfo(path=dstPath)
                
            else: # file larger than chunkSize. Use files_upload_session_append_v2
                uploadSessionStartResult = dbx.files_upload_session_start(fp.read(chunkSize))
                cursor = dropbox.files.UploadSessionCursor(session_id=uploadSessionStartResult.session_id,
                                                        offset=fp.tell())
                commit = dropbox.files.CommitInfo(path=dstPath)

                while fp.tell() <= fileSize:
                    if ((fileSize - fp.tell()) <= chunkSize): # file chunk append complete
                        print("COMPLETE CHUNKS")
                        uploadEntryList.append(files.UploadSessionFinishArg(cursor=cursor, commit=commit))
                        break
                    else:
                        print(fp.tell())
                        dbx.files_upload_session_append_v2(fp.read(chunkSize),
                                cursor)
                        cursor.offset = fp.tell()
            uploadEntryList.append(files.UploadSessionFinishArg(cursor=cursor, commit=commit))

    print( dbx.files_upload_session_finish_batch(uploadEntryList) )


srcDir = "C:/Users/alpha/Documents/scratch/LIGHTS - Copy"
srcFiles = [join(srcDir, f).replace('\\', '/') for f in listdir(srcDir) if isfile(join(srcDir, f))]
dstDir = "/scratch/poopOne"
dbx = DropboxTeam(DROPBOX_TOKEN).as_admin(ADMIN_ID)
batchUpload(srcFiles, dstDir, dbx)
