Macro/url query parameter malfunctioning in RM web service.

pari1234

Hi there,

 

I have setup a rapidminer webservice with a url query parameter bound to a macro with a default value in the underlying process context. But when testing the web service (in admin console or calling the API url), I enter a different value for the query parameter (or in other words the macro in the underlying process), I still get results for the default value of the macro and not the new value that I just tried to pass. It seems the user entered values are not getting passed to the underlying process. So when testing, even if I do not pass anything, I still get results with the default value for the macro. Any ideas why this might be happening? I remember there was an old video (RM 5 if I recall correctly) about this on youtube but I just can't find it.

 

 

Thank you very much!

Hi @sgenzer, sorry about not being able to reply sooner and thank you very much for taking the time to go through this process. You are right about the server logs error messages and access tokens. Anyways, I made some changes to the process such that instead of passing url parameters, I now just send a JSON array in a POST request to the RM webservice API. 

[{
	"platformName": "twitter",
	"username": "rel8edto"
}, {
	"platformName": "facebook",
	"username": "rel8edto"
}]

This then gets converted to an example set using the read document, JSON to Data and De-Pivot operators and using appropriate filters and extracting macro inside the process, I can pass the username to the appropriate branch (facebook or twitter). I still haven't figured out exactly what happened with being able to passing macros. I created an identical server client setup at home and it worked just fine. So I'm guessing something might have led to a bug in our RM Server at some point. But thank you very much for your help. :smileyhappy:
