Sir I’ve updated the KNIME version but I can’t found my required Nodes. Please help me out there

Did you reload the partner site as described in the linked thread? Many users have found that after doing that, issues are resolved when trying to install extensions.

I am facing is that I cant even found these required nodes in KNIME respiratory

You should be able to drag-and-drop them from the KNIME Hub, which will prompt installation of required extensions. For example: JSON Path

can you help me out to find following nodes:

  1. HTTP Request node to make a POST request to the Alpaca API endpoint for creating orders.

  2. JavaScript Snippet node to construct the JSON payload for the POST request and to handle the API response.
