Hi, The ‘error unmarshalling return’ refers to having different versions of the Denodo Platform Tools. You may check the versions of the tools through the Denodo Platform Control Center and ensure that they are the same versions. The ‘nested exception is: java.io.EOFException’ error indicates that the Scheduler Job is encountering an unexpected end of file error. You can look into the Scheduler Log to view more information of the error you are receiving. You may refer to the similar community questions [Unmarshalling error](https://community.denodo.com/answers/question/details?questionId=90670000000XcUKAA0&title=Unmarshalling+error) and [Extractor Errors: [Error unmarshaling return header; nested exception is: java.io.EOFException]](https://community.denodo.com/answers/question/details?questionId=9060g000000L6uhAAC&title=Extractor+Errors%3A+%5BError+unmarshaling+return+header%3B+nested+exception+is%3A++%09java.io.EOFException%5D) for more information Hope this helps!
