Hello @kotlapullareddy ,

could you please tell me what version of Analytics Platform and KNIME Executor are being used?
Could you please check that your KNIME Executor and Analytics Platform are on the same version?
This node was implemented in AP 4.7.x as a base node meaning this extension is already included in KNIME Analytics Platform, there is no need to install it, so it should not be missing. (Maybe the workflow was built with 4.7.x version where this node is available / improved but the executor is on an older version where this node is not available?)
So please upgrade your executor to the same version (4.7.x). Speaking of upgrading to avoid any issues, we strongly encourage using a version of KNIME Executor from the same release line as your KNIME Server installation. See the product compatibility matrix here.

Did it help to resolved this issue?

Hey Dora_gcs,

Here is my versions
KNIME analytics platform - 4.7.3
KNIME SERVER Version: 4.15.2

so we need to update KNIME server to latest version (4.16)? is it mandatory ?
