Steps to reproduce:
Steps followed:

1. Import the relevant modules:
   from influxdb_client import InfluxDBClient, BucketRetentionRules
2. Declare the required fields:
   url = "http://localhost:8086" token = "my-token" org = "my-org"
3. Attempt creating a new bucket:
   client = InfluxDBClient(url=url,token=token)
retention_rules = BucketRetentionRules(type="expire",every_seconds=3600)
   #create the bucket
   created_bucket = client.buckets_api().create_bucket(bucket_name="bucket-by-python",retention_rules=retention_rules, org=org)

Link to the example followed: https://github.com/influxdata/influxdb-client-python/blob/master/examples/buckets_management.py

Expected behavior:
A new bucket is created

Actual behavior:

Hi @AbhigyaShridhar,

thanks for using our client.

The error is cause by missing organization with name 'my-org' in your InfluxDB database. The error message is not clear... so I will prepare PR to clarify problem.

Regards
