Hi guys, i'm running purchased version of EmailParser v4.5, getting the error "Error. An invalid character was found in the mail header", i believe the issue is caused by the "TO" field being "undisclosed-recipients:". Is there any way I can validate the "TO" field value in custom script? or is this validation done internally by the application?

Below is the parser log with the Run Script process code. Please help.

The parser produced the following results:

Saving attachments:

The following fields will be available for the next automated processes:

This is a bug of the version 4.5 and I think (although I am not completely sure) it was addressed in version 4.6. If you update Email Parser it will probably work.

Note that 4.6 uses a slightly different namespace for scripts. You will need to replace this:
using EmailParser.Logic.ScriptingInterface;

public class MyAction : ScriptBasedAutomatedProcess
with this:
using EmailParserBackend.ScriptingInterface;

public class MyAction : ScriptBasedAction
Please, post here again if the problem persists.
