On the field named in the error message, which in the example is "Martial_Status__c", you have left "Strictly enforce picklist values" checked. This is a new Salesforce field that will require that any values that populate this field, must be a value defined in the field definition. This means that if you have a single or multi-select option in your form that you do not have in your field definition, the mobile user will receive this sync error.
To resolve this issue:
- Uncheck "Strictly enforce picklist values" for this field.
- Ensure that you single-select values in your form are listed as values in your field definition. For this example I would either need to add "Divorced" as a value in my field definition, or remove that option from the form question.
I would recommend unchecking the "Strictly enforce picklist values" checkmark box for any picklist and multi-picklist fields that are going to be written to by TaroWorks. By unchecking this, your mobile user will never receive this sync error for this field.
