ALC-DSC-005-000: Not Serializable


Level 4
What does the message "ALC-DSC-005-000: Not Serializable" mean? I am trying the simple "Sending an email with an attachment" walkthrough in the training manual and I receive this error when trying to invoke the process.

Does this mean that a configuration setting in the "Read Document" operation or the "Send With Document" operation is in error?

That usually means that you have a type mismatch in your variables. The process wants a document and you pass it XML or something like that.

You can check the step, in which you get the error, from adminui under

Services > Process Management > Stalled Operation Errors.

You are probably not setting a variable, typed document, as input/output.
