Working on my NetScan script for our Arista AP's still and when trying to execute a http [DELETE] I get the above error when following the Delete documentation here which suggests I can just call the URL and header.Currently this is just using the collector debug !groovy command If I then try with blank payload I get a different error: exception:java.lang.NullPointerExceptionFirst Error with no payload in call: exception:groovy.lang.MissingMethodException: No signature of method: com.santaba.agent.groovyapi.http.Client.delete() is applicable for argument types: (java.lang.String,
