CORS issue with Thingworx and REST calls

Hello everyone,

 

I am facing the famous CORS issue when making post calls from my java script to the Thingworx Server. To be specific, this is the error message: "...has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

 

I tried to add the CORS filter to the tomcat web.xml as described in this thread and I am still facing this problem. I am using the Trial-Version for Thingworx by the way.

 

Any ideas what could be the reason?

Any help is appreciated very much.

 

best Regards,
Dominik

Hello, Dominik:

 

   Is it possible you can share the fragment you added to the web.xml?

You can message it to me privately if you wish.
