Amazon S3 Connection Node Missing – Cannot Configure Custom Endpoint for S3-Compatible Storage

Description:

I am trying to connect KNIME to an S3-compatible storage service (Optum internal S3) that requires a custom endpoint (e.g., https://)).

However, in my KNIME installation:

*

I only see Amazon S3 Connector and Amazon S3 Connection (Legacy) nodes.

*

The legacy node fails because it does not allow specifying a custom endpoint override.

*

The Amazon S3 Connector dialog only shows “Working Directory” and does not provide any fields for Access Key, Secret Key, or Endpoint configuration.

Expected Behavior:

• Ability to configure Access Key, Secret Key, Region, and Custom Endpoint in the connection node (as documented in older KNIME versions).

Actual Behavior:

*

No option to set credentials or endpoint in the new connector dialog.

*

Legacy node does not support custom endpoints, so connection fails with:

Connection to s3://<bucket>@us-east-1 failed. Check your Access Key ID / Secret Key.

Questions:

1.

Has the Amazon S3 Connection node been removed or replaced in the latest KNIME version?

1.

How can I configure custom S3 endpoints in the current KNIME setup?

Environment:

*

KNIME version: [5.5.1]

*

OS: [MacOS]

*

Extension: KNIME Amazon S3 Connector, KNIME Amazon S3 Connection (Legacy)

Feature Request:

Please add support for custom endpoints and credentials configuration in the new Amazon S3 Connector node or provide guidance on the recommended approach for S3-compatible storage.
