Error adding file

[Ana_Paula_Lopes]

Hello everyone, I am having the following problem: When I add the file it gives an exception of PropertyNotFoundException, I understand that something is missing, but I do not know who ...

**Error in the second line

Blob fileBlob = new Blob(file);
fileBlob = nuxeoClient.automation().newRequest("Blob.AttachOnDocument").param("document",   docCriado).input(fileBlob).execute();

error:

Exception:
  status: 500
  code: org.nuxeo.ecm.core.api.model.PropertyNotFoundException
  type: Error
  exception: Failed to invoke operation: Blob.AttachOnDocument

thanks
