WSO2 ESB Tutorial Error - wso2

Question

I found the exact same problem here but there was no answer, and I can't move on with this without an answer.
WSO2 Start - up (Sending Simple Message)
The sample I'm trying to use is hosted in WSO2 App Cloud at http://wso2training-restsamples.wso2apps.com, and the tutorial is this one: https://docs.wso2.com/display/ESB500/Sending+a+Simple+Message
As far as I know I followed the tutorial to the letter, but when I get to sending the GET request, although it logs in the Eclipse console, on my console, after doing this command:
curl -v http://localhost:8280/healthcare/querydoctor/surgery
I get this
Exception occurred :Illegal character in path at index 12: /healthcare/{uri.var.category}* Connection #0 to host localhost left intact

Answer 1

You have a typo (an extra space at the end) in your endpoint url-template. Be careful not to include whitespaces in the beggining or end of your templates.
uri-template="http://wso2training-restsamples.wso2apps.com/healthcare/{uri.var.category}"
Remove it and ou should get the expected output.
