Take a look to your logs for the exception that occurred immediately prior to this one.

Have you tried a new content type?

What version/build?

Hi,

As i did not find any obvious problem in the request data, variables and content types, i have redone the workflow from scratch (without using snipets or existing content type) and now it's works !

Thanks for your help
