Create a MinIO Bucket in NiFi - Using ExecuteScript processor and (J)python

Question

The 5 S3 related processor present in NiFi cannot create a Minio Bucket.

• ListS3
• PutS3Object
• DeleteS3Object
• FetchS3Object
• TagS3Object

So I tried to use the ExecuteScript processor and import the python minio module inside of it

In order to do that I install pip3 on my CentOS machine and did pip3 install minio(it installed it in /usr/local/lib/python3.6/site-packages/).

Then in my ExecuteProcessor I set the following configuration :

Script Engine : python
Script File : No value set
Script Body :

from minio import Minio
from minio.error import (ResponseError, BucketAlreadyOwnedByYou,
                         BucketAlreadyExists)

minioClient = Minio('minio',
                  access_key='XXXX',
                  secret_key='XXXX')

Module Directory: /usr/local/lib/python3.6/site-packages/

But I keep getting this error

No module named builtins in at line number 1

Full error :

ExecuteScript[id=3a3e689a-0170-1000-fa4d-b0874062b8cc] ExecuteScript[id=3a3e689a-0170-1000-fa4d-b0874062b8cc] failed to process due to javax.script.ScriptException: ImportError: No module named builtins in at line number 1; rolling back session: org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: ImportError: No module named builtins in at line number 1

Hypothesis 1 :

Of what I understand NiFi use Jython and then cannot use C-related Python module, I couldn't find the confirmation that minio-py was one of them but it seems to be the most relevant reason.

is there something I'm missing ?
