Additional Document cannot sent with SDK

[youssefAndro]

Summary

I tried to create a Token for an Individual Account, i filled all fields as well as "Document" and "AdditionalDocument".

When i call function "STPAPIClient.shared.createToken" i get "400 ERR" <<parameter_unknown - account[individual][verification][additionalDocument]>>

Code to reproduce

    let individualParam =  STPConnectAccountIndividualParams()
    individualParam.firstName = "firstName"
    individualParam.lastName = "lastName"
    individualParam.email = "email@gmail.com"
    individualParam.phone = "phone"
    individualParam.dateOfBirth = DateComponents(calendar: Calendar.current, year: 1990, month: 11,day: 10)

    individualParam.address = STPConnectAccountAddress()
    individualParam.address!.line1 = "address_line_1"
    individualParam.address!.city = "address_city"
    individualParam.address!.state = "address_state"
    individualParam.address!.country = "Fr"
    individualParam.address!.postalCode = "30000"

    var individualVerification = STPConnectAccountIndividualVerification()
    
    var verificationDoc = STPConnectAccountVerificationDocument()
    verificationDoc.front = "file_1J9tkXBeJFfQNTxxKS3NJacB"
    verificationDoc.back = "file_1J9tkeBeJFfQNTxxpV3sHQyk"
    individualVerification.document = verificationDoc
    
    var verificationAdditionalDoc = STPConnectAccountVerificationDocument()
    verificationAdditionalDoc.front = "file_xxxxxxxxxxxx"
    verificationAdditionalDoc.back = "file_xxxxxxxxxxxx"
    individualVerification.additionalDocument = verificationAdditionalDoc
    
    individualParam.verification = individualVerification
    
    let accountParams = STPConnectAccountParams(tosShownAndAccepted: true, individual: individualParam)

    STPAPIClient.shared.createToken(withConnectAccount: accountParams!) { (accountToken, error) in
                if let error = error {
                    // display an error to your user
                    DebugHelper.debug("Token error", error.localizedDescription)
                }else {
                    DebugHelper.debug("Token success", accountToken?.tokenId)
                }
