Hello Stackoverflow community.
Currently, I found that Umbraco doesn't have an option to support the enterprise invisible reCaptcha. After following a bit along I did came across this documentation where we can create custom field type and have a custom validation logic.
What I have done so far :
Add a new class
ReCaptchaEnterprise.cs
using System;using System.Collections.Generic;using System.Linq;using Microsoft.AspNetCore.Http;using Umbraco.Forms.Core.Enums;using Umbraco.Forms.Core.Models;using Umbraco.Forms.Core.Services;namespace FormsExtensions{ public class ReCaptchaEnterprise : Umbraco.Forms.Core.FieldType { public ReCaptchaEnterprise() { Id = new Guid("e3ab6a21-bc99-4cb8-999e-ad01203d61bd"); // Replace this! Name = "ReCaptcha Enterprise"; Description = "Render a custom reCaptcha enterprise field."; Icon = "icon-autofill"; SortOrder = 10; FieldTypeViewName = "FieldType.ReCaptchaEnterprise.cshtml"; } // Custom validation in here which will occur when the form is submitted. // Any strings returned will cause the submission to be considered invalid. // Returning an empty collection of strings will indicate that it's valid to proceed. public override IEnumerable<string> ValidateField(Form form, Field field, IEnumerable<object> postedValues, HttpContext context, IPlaceholderParsingService placeholderParsingService, IFieldTypeStorage fieldTypeStorage) { var returnStrings = new List<string>(); if (!postedValues.Any(value => value.ToString().ToLower().Contains("custom"))) { returnStrings.Add("You need to include 'custom' in the field!"); } var reCaptchaResponse = context.Request.Form["g-recaptcha-response"].ToString(); Console.WriteLine("+++++++++++++++++++++ReCaptcha response+++++++++++++++++++++++++++" + reCaptchaResponse); // Also validate it against the default method (to handle mandatory fields and regular expressions) return base.ValidateField(form, field, postedValues, context, placeholderParsingService, fieldTypeStorage, returnStrings); } } }Partial View

<div class="g-recaptcha" data-sitekey="<site-key>" data-size="invisible"></div>I am able to add the reCaptcha enterprise in the form. However, when I go to Content and add it over there via Rich Text Editor > Macro the following exception is thrown.
Received an error from the serverAn error occurredCannot bind source type Umbraco.Forms.Web.Models.FieldViewModel to model type Umbraco.Cms.Core.Models.PublishedContent.IPublishedContent.

I have no idea what is going wrong I am debugging the issue since last 2 days cannot find any solution.
I will really appreciate any leads to resolve this issue or if you can share your experience regarding how you created a custom field in Umbraco. Thank you so much for your time for reading through my question until here.
I have tried following other packages that have done something similar to implement reCaptcha but it is of no help until now.
