New lead who filled out a MKTO form was not synced to SFDC during a flow step - MKTO reason - Invalid Cross reference key- Record type ID: This ID is not valid for the user.
In the activity history for the lead it says that the SFDC campaign status update couldn't happen because the lead was not a SFDC Lead/Contact type.
I'm confused because I'm trying to sync them to SFDC so they can become a Lead type.
What is the order of your workflow? If the lead isn't in SFDC (hence, not a SFDC lead/contact) then they can't be added to the campaign. Do you have a "sync lead to SFDC" step set up in the workflow before adding them to the campaign?
It sounds like there could be some permission issues in SFDC. I would double check to make sure that the Marketo-SFDC sync user in SFDC has been granted access to all relevant record types for the lead/contact objects. Possibly a record type is being specified somewhere that the user does not have rights on.
Not 100% sure but the first error message suggests this could be the problem.
