Pushing JSON files to elasticsearch using Python Script: Works but does not show up in Kibana

Question

Background Information:

Hi,

I've been trying to push JSON files into Elasticsearch using a custom script, the script runs and finishes - however, when I check Elasticsearch and Kibana the index exists but none of the docs that I'm sending are uploaded. I've done this a countless number of times. Not sure where I am going wrong since this has worked before -

Code

#Change the IP as desiered 
es = Elasticsearch(
     ['localhost'],
     timeout=420000,
     port=9200
 )

print ("Start")

#Append to this list if all files from a folder have been uploaded 
done_list = []
filenames = os.listdir("/home/directory/file_json")
print(filenames)

for current_folder in filenames:
    for f in glob.glob("/home/directory/file_json/"+current_folder+"/*.json"):
        print("File Open")
        MyFile = open(f).read()
        print("Bulking - "+f)
        es.bulk(MyFile,"test","_doc")
        print("done elasticsearch")
  done_list.append(current_folder)
  print(current_folder + " done")

print ("Finished")

If anyone could let me know if this has some sort of error or maybe something I'm missing that would be greatly appreciated.
