I recently uncovered this error in our system, and haven't been able to figure out why it is occurring. I have checked our field mappings, but that seems fine. This error does not occur on every record, so I don't understand why it happens on some of them. I have manually updated some records by copy/pasting the Company from the Lead in Salesforce over to the Lead record in Marketo. Silly. Not sure how to fix this via a batch either.... Would love any tips or suggestions.
