Sync Lead to SFDC - Failed: FIELD INTEGRITY EXCEPTION:

[Anonymous]

My leads from Bolivia in Marketo (Bolivia in the country field) are not syncing to Salesforce.com.

Marketo exception message says:

Failed: FIELD_INTEGRITY_EXCEPTION: There's a problem with this country, even though it may appear correct. Please select a country from the list of valid countries.: Country

Is anyone experiencing this kind of issue?

The Country field is a picklist and the value you are pushing to SFDC does not match the value in SFDC. SFDC is protecting this field from outside values.

Please check your picklist.
