During an SFDC sync, some records within my instance fail to sync, with the following error:
Failed: FIELD_INTEGRITY_EXCEPTION: There's a problem with this country, even though it may appear correct. Please select a country/territory from the list of valid countries.: Country
I've seen some other posts on the community, and I've contacted Marketo support, but I'm unable to successfully troubleshoot this. The records in question have a blank country value, and our SFDC admin is able to confirm that there doesn't seem to be any restriction that would prevent records/leads from being created in SFDC if no country value is present (I can create one, manually, as an SFDC user, and I can create one without a Country value via the Data Loader desktop client also).
Has anyone encountered this before?
