When data has been entered into HubSpot in an incorrect format, you might receive the error shown below when working with the HubSpot Connector:
 
Date Format error – “Unable to format the data” from HubSpot Source Connector
Unable to format the data '{
  "value": "10:31 PM UTC"
}' for Contact.hs_analytics_first_timestamp.
 
In this error message the value was not in a valid date format. This error can display in either a Query Block on the Preview tab or in the Execution History Detail for a Solution. Some HubSpot fields are read only and are intended to be set or populated by HubSpot. Due to a HubSpot issue, sometimes users have entered invalid data in one of these fields. When the field is read by the TIBCO Scribe® Online HubSpot Connector, HubSpot detects the incorrect field properties and the error is generated. For more information, search for the error or its components in the HubSpot support webpage.
