# Error 400 – Invalid resource (dropdown field)

 * Hi there,
    we connect several forms to Mailchimp with this plugin and it has 
   been working great. However, suddenly we get error logs on all submissions that
   contain a country drop-down (which worked before, too). We assume this is happening
   due to some update but we cannot find any way to fix it. From the log:
 * title: Invalid Resource
    status: 400 detail: The resource submitted could not
   be validated. For field-specific details, see the ‘errors’ array. errors[{“field”:”
   merge_fields.COUNTRY”,”message”:”Data did not match any of the schemas described
   in anyOf.”}]
 * Now this data was submitted:
 * Email: [removed]
    Country (required): {“value”:[“Afghanistan”],”label”:”Country(
   required)”}
 * Whereas Afghanistan was just a test. Previously under the field “Country (required)”
   ONLY the item “Afghanistan” would be submitted without the other text like “{“
   value”:[” etc.
 * Any hint how to solve this would be greatly appreciated.
