**Message:**  
 `Property 'zip' was provided with an invalid value.`  
 Or:  
 `Invalid phone number format.`

**Cause:**  
 Wrong data type or invalid formatting for a field (e.g., string instead of integer, incorrect date format, invalid email).

**Fix:**

- Validate and sanitize data before sending.
- Follow HubSpot’s data format requirements (e.g., ISO 8601 for dates).
