SSIS Event Handler - How do I get the entire error message?

I've set up a data flow task with a source component (ODBC to Salesforce) that writes rowcounts and any raised error messages to a table.

I've created an OnError event handler that writes the message from System::ErrorDescription to a variable, and then that variable is written to the table.

My problem is that System::ErrorDescription doesn't have the interesting error message, but the summary. These are the messages being generated in the Progress tab:

• [SRC - Extract Account [6]] Error: System.Data.Odbc.OdbcException (0x80131937): ERROR [HY000] INVALID_LOGIN: Invalid username, password, security token; or user locked out.etc, etc,etc
• [SSIS.Pipeline] Error: SRC - Extract Account failed the pre-execute phase and returned error code 0x80131937.

System::ErrorDescription only has the [SSIS.Pipeline] error ("SRC - Extract Account failed the pre-execute phase and returned error code 0x80131937"). How do I return the more detailed [SRC - Extract Account [6]] message?

Thanks, Jason

You could also just query your SSISDB to get the error.

Use event_name to find your error

Try this:
