I am using the Get Request node. For each line of a Data Table I construct one URL (based on end user input) to call on an internal REST API.
When the URL is ok, I get my results in a JSON body result.
But sometimes there is an error in the URL (it could happen because the user has selected the wrong parameter for expl).
With Postman I will obtain the error status (ie 400, 404, or others…) and I will obtain a JSON results with a message like this:
“message”: “Your request is missing a parameter: MinimumAmount”
My problem is that I cannot obtain this JSON results with the Get Request node. In all cases, with various status errors, I obtain the Status (perfect) and a body that is empty and recognized by Knime in the binary format (very bad).
@ScottF has shared the post which is your anwer, but just to make it easier for you, I would like to let you know that since KNIME 4.0 the update site for Palladian has been changed so you have to add this update site to install the extension (KNIME 4.1): http://download.nodepit.com/palladian/4.1
The update site to install the corresponding extension for each node is available at the bottom of its NodePit page.
1-the licence for the Palladian node has changed so I will have to check it
2- I am planning to use the node for rest call in components that I will share. That is why I am trying to have the less possible dependencies.
So, my first question around the Get Request node is still opened.
