Test Amazon S3 connection

Christophe35

I setup a Amazon S3 connection to a Minio server using an http endpoint and using path style option.
When i click on the TEST button , the following error appears:
Connection failed: Bad Request (Service: Amazon S3; Status Code: 400; Error Code: 400 Bad Request; Request ID: 17EC370F655CA6AA; S3 Extended Request ID: 7ce489d5d50db7f29e4b69d22e30326651db985b78b63934915c308acf08654e; Proxy: null)

A minio mc client with trace option shows this error corresponds to an incorrect bucket name __dku_test_bucket:

According to the AWS S3 bucket name convention (https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html) , the underscore in bucket name is not allowed.

How do i configure the bucket name used by the TEST button on a AWS S3 connection ?

Dataiku version 13.1.0
Minio server version RELEASE.2024-04-18T19-09-19Z
Minio mc version RELEASE.2024-08-13T05-33-17Z

Operating system used: Rocky 8

Are you setting the Bucket and Default Bucket S3 connection properties to a valid bucket name?

If set the Bucket in Path Restrictions then the Default Bucket in Managed datasets & folders disappears.
Either i set the Bucket in Path Restrictions or the Default Bucket in Managed datasets & folders , the TEST button produce the same error.
