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

[pragichaudhary]

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?

2. 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.

Hi @pragichaudhary , welcome to the KNIME Forum. I haven’t used the S3 connectors myself but does the “Generic S3 Connector” node do what you require? This should be part of the Amazon Cloud Connectors extension.

Thankyou so much for the solution. It worked for me!
