I have a .net 7 web api where I’m trying to validate addresses. I believe I have all the models correct even the response body. I’m unable to get any kind of response back. It works on postman but I cannot get it to work using my api. Can someone please tell me what I’m doing wrong? I’ve even tried asking chatgpt but to no prevail.

(yes I have everything set up from google maps, like I said it works just fine on postman)

Here is the link to the api:
https://developers.google.com/maps/documentation/address-validation/requests-validate-address

namespace WebApplication1.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ValidateAddressController : ControllerBase
    {
        private readonly ILogger<ValidateAddressController> _logger;
        private readonly HttpClient _httpClient;

        public ValidateAddressController(ILogger<ValidateAddressController> logger, HttpClient httpClient)
        {
            _logger = logger;
            _httpClient = httpClient;
        }

        public class AddressValidationRequest
        {
            public Address? Address { get; set; }
        }

        public class Address
        {
            public string? RegionCode { get; set; }
            public string[]? AddressLines { get; set; }
        }

        public class AddressValidationResponse
        {
            public string FormattedAddress { get; set; }
            public string AddressType { get; set; }
            public bool Valid { get; set; }
            // Add other response fields as needed
        }

        [HttpPost("GetFormattedAddress")]
        public async Task<IActionResult> ValidateAddress([FromBody] AddressValidationRequest request)
        {
            if (request?.Address == null)
            {
                _logger.LogWarning("Request or Address is null");
                return BadRequest("Request or Address cannot be null");
            }

            var requestUri = $"https://addressvalidation.googleapis.com/v1:validateAddress?key=<MY api key>";

            try
            {
                _logger.LogInformation("Sending request to Google Maps API");

                var response = await _httpClient.PostAsJsonAsync(requestUri, request);
                if (response.IsSuccessStatusCode)
                {
                    var addressValidationResponse = await response.Content.ReadFromJsonAsync<AddressValidationResponse>();

                    if (addressValidationResponse == null)
                    {
                        _logger.LogError("Response content is null");
                        return StatusCode(500, "Response content is null");
                    }

                    _logger.LogInformation("Successfully received response from Google Maps API");
                    return Ok(addressValidationResponse);
                }
                else
                {
                    var errorResponse = await response.Content.ReadAsStringAsync();
                    _logger.LogError($"Google Maps API error: {response.StatusCode} - {errorResponse}");
                    return StatusCode((int)response.StatusCode, errorResponse);
                }
            }
            catch (Exception ex)
            {
                _logger.LogError(ex, "An error occurred while validating address");
                return StatusCode(500, "Internal server error");
            }
        }
    }

I’ve tried updating the models, using the two different types of body models, and it just doesn’t seem to want to work with my code.
