I have created a index like

```
> PUT new_index_blob
> {
> "mappings": {
> "properties": {
> "name": {
> "type": "text"
> },
> "blob": {
> "type": "binary",
> "store": true
> }
> }
> }
> }

```

When I am trying to store a Base64 encoded binary value from dev tool like below , it working fine

```
> PUT new_index_blob/_doc/1
> {
> "name": "Test",
> "blob": "U29tZSBiaW5hcnkgYmxvYg==" 
> }

```

I am able to get/search the same from dev tools

`GET /new_index_blob/_source/1`

But when I am trying to store the same using python REST API its not working , not giving any error too , below code snippet

```
path = "C:\\Users\\Administrator\\Desktop\\POC_LOG_Collector\\"
name= "100.97.16.31_2020_Jul_17_09_14.zip" # 53 MB
zip_file_path = os.path.join(path, name)
elastic_url= "http://%s/%s/%s"%(
  "localhost:9200",
  "new_index_blob",
  "_doc/2"
)
try:
    data = open(zip_file_path, "rb").read()
    encoded = str(base64.b64encode(data))
    upload_data={}

    upload_data["name"]=name
    upload_data["blob"]=encoded
except Exception as e:
    print(str(e))

try:
    resp_elastic = requests.put(
            elastic_url,
            headers=headers,
            data=json.dumps(upload_data),
            verify=False
    )
    print("ES Entry completed for {}".format(name))
except Exception as e:
    print(e)

```

What is the mistake I am doing . Also even after inserting it from Dev Tools the Doc count is showing 0 , is it expected for **datatype**  **binary** with **store true**  
.

I have fixed it now , it was byte string conversion issue. ES was expecting base64 encoded string and I was sending bytes .
