Mule-APIkit with baseUriParameter truncates resource path thus erroring out as 'resource not found'

Question

Can anyone please suggest/correct me here on how to get APIkit Router working with baseUriParameter. If the path in the HTTP Listener Connector is hardcoded like /api/process/30001/*, it all works fine. APIKit Router is able to route the requested resource path. But, when there is a placeholder in the HTTP Listener Connector path like /api/process/{clientID}/*, an error is thrown at APIkit Router as No resource found.

From the stacktrace below, I could see that the request resource path is truncated, for example, /sample becomes just ple and I couldn't find the reason why. Through debugging, I could see the complete request URI. Image from debug mode to see the complete request path.

I have tried a few other options like:

Checking 'keep raml base uri' in router config
Unchecking box 'parse Request' in Advanced tab of HTTP Listener Connector

I have checked through this, too, to be sure that my RAML conform with raml-template-uris and uriparams.

I found this in the MuleSoft docs:

In API Gateway Runtime 2.x and earlier, APIkit is designed to work very tightly with RAML interfaces, but does not automatically import the following items from the RAML definition:

securitySchemes

protocols

baseUriParameters

So, how do I import baseUriParameters? How do I make it work?

I've been stuck with this issue for quite a long time, so any help is greatly appreciated. Please correct me if I missed something. Thanks a lot!

Which version of Mule Runtime are you using? – aled Jul 09 '19 at 18:39 — aled, Jul 09 '19 at 18:39
