If you're seeing the error:

"Property values were not valid"
This typically occurs when your CRM (HubSpot) expects a specific value format for a field (for example a picklist/dropdown), but the value that UpLead sends doesn’t match the allowed values.

What Causes This?

Here are several root causes of this error:

  1. State / Country codes vs full names
    UpLead by default may send country or state codes (e.g., US, CA, NY), whereas HubSpot’s corresponding property may be configured as a picklist expecting full names like United States, Canada, New York. When mismatched, HubSpot rejects the value.

  2. Picklist (dropdown) field value not in the allowed set
    If the HubSpot property you are pushing to is configured as a picklist (dropdown or enumeration), and the value that UpLead sends is not one of the allowed options, you’ll also receive the “Property values were not valid” error.
    This often happens for custom fields such as “Industry”, “Customer Type”, “Region”, etc., where the set of allowed dropdown values is limited. Because you may not be able to change the picklist options on the HubSpot side easily, the upstream data must match one of the allowed values exactly.

  3. Field-type or mapping mismatch
    Sometimes the issue arises because the field in HubSpot is of one type (dropdown, multi-select, etc.), but the mapping from UpLead treats it as a free text or string. The mismatch between the expected type and the value format leads to validation failures.

How to Fix It

If you're encountering this issue, follow these steps:

  1. Depending on which scenario applies, follow the appropriate steps:


    ​For State / Country code mismatches:
    ​

    1. Contact UpLead Support and open a ticket.

    2. Provide the message:

      “I’m encountering validation errors due to state/country field mismatches. Please update my integration mapping to send country and state names (not codes) for the following accounts: [list of account emails].”

    3. UpLead Support will adjust your mapping configuration on the backend so that full names (e.g., United States, California) are sent, which match the HubSpot picklist. support.uplead.com


    ​For Picklist fields (Industry, custom dropdowns, etc.):
    ​
    Because HubSpot may restrict what picklist values are allowed, and you might not have full control over that set, we recommend the following workaround:

    1. Identify the picklist property in HubSpot and review its allowed values.

    2. Check what value UpLead is sending for that field and see if it matches one of those allowed options exactly (same spelling, same case, same option).

    3. If the value does not match the allowed set, then you can perform the following actions to remap it:

      • Exclude the field: Use UpLead’s “Exclude a property from your CRM” setting so that you avoid pushing that field altogether.

      • Remap to a string/text field: Instead of mapping to the picklist property, map the value to a free-form text (string) property in HubSpot so that any value is accepted.

    4. Update your UpLead export/integration configuration accordingly.


    ​For field-type or mapping mismatches:
    ​

    1. In HubSpot, check the property details: is it a dropdown/picklist, multi-select, or free text?

    2. In UpLead, check how you are mapping the source value: are you sending text, codes, list of values?

    3. Align them: either change the HubSpot property to accept the format (if possible), or adjust your UpLead mapping to send a format which HubSpot accepts.

    4. After adjusting, retry the export/push and verify that the error is resolved.

Temporary Workaround

If you need to continue exporting while you resolve the mapping issues:

  • In UpLead, go to Profile → Customize Integration (or equivalent settings)

  • Under the relevant object (Contact or Company) uncheck the problematic fields (for example, Country, State, or the custom picklist field such as Industry) so they are excluded from the export/push.

  • Click Save.

Note: This means you’re skipping those fields entirely in the export, so those particular values won’t go into HubSpot, but it allows the export to succeed without blocking due to validation errors.

Preventing Duplicate Companies

Sometimes you may see duplicate companies being created in HubSpot when pushing contacts from UpLead. The steps to avoid this are outlined in the How to Avoid Duplicate Companies when Pushing Contacts to HubSpot article:

  • In UpLead: disable company export so that UpLead does not create new company records.

  • In HubSpot: enable automatic company creation/association so that contacts are correctly associated with existing companies by domain rather than creating duplicates.

  • Why this works: When UpLead only pushes contacts and relies on HubSpot’s company-association logic, you reduce the risk of duplicate company records and maintain better data consistency.
