In a query that culminates in a curl command on a resuult, when the result set if empty, it's not possible to prevent the curl command from trying to execute.
A workaround I am using is to set the urifield rather than using uri, as then when there are not results and no urifield, the curl call just returns an error saying no URL specified.
However, it would be nice to be able to indicate the curl command do nothing when the results.len = 0. Currently when results is 0, it just goes and tries to run the curl.
My search is running as a saved search and all iterations will record an error when there are no results.
This is the intended behavior
if len > 0... act like a streaming command
else... act like a generating command
this lets the command have the flexibility to run once per result fed to it, or to just run one time all by itself.
Can you use additional logic to get around it?
perhaps a subsearch with eval if/case which returns the curl command OR "null"
Instead of the opposite direction you're going where a null is fed to the curl command.
