Description:

When a cross origin resource sharing (CORS) request for a PUT operation is sent to a REST service built with the plug-in dispatch activity, there is a problem when the request is sent from a browser such as Chrome or FireFox because of the different behavior of those browsers in sending the request. The same request works fine when sent from IE.
Symptoms:
When the request is sent from Chrome or FireFox, that request is not handled properly. A similar error is reported in the client.
Cause:
The browser sends an OPTIONS operation before it sends a PUT operation. If the OPTIONS operation is not handled correctly in the REST service, the above error is reported in the client and the following PUT request cannot go through.

Add the function in the project to handle the OPTIONS operation. This can be done by adding an additional workflow in the BusinessWorks process to receive and reply the request with the OPTIONS operation method. Also, HTTP connection resource should be in the type of HTTP Component to allow HTTP receiver to get the OPTIONS request.

TIBCO ActiveMatrix BusinessWorks Plug-in for REST and JSON HTTP PUT operation in plug-in dispatch does not work when a request is sent from Chrome or FireFox.
