ABP FindByNameOrEmailAsync method return null value

Question

When I call the FindByNameOrEmailAsync method from postman it returns the user. But once I send the values through UI, the method returns null. Though the value is bound to the usernameOrEmailAddress variable and come to the method, it returns null.

Can someone help me?

   <input type="email" id="emailInput" class="form-control" maxlength="255" placeholder="Enter your email" required />
   <button id="requestResetEmail" class="btn btn-primary btn-block btn-flat">Request password reset</button>


      abp.ui.setBusy(
        $('#LoginArea'),
        abp.ajax({
            url: abp.appPath + 'Account/ForgotPassword',
            type: 'POST',
            data: JSON.stringify({
                usernameOrEmailAddress: $('#emailInput').val(),
                returnUrl: window.location.hash
            })
        })

  public async Task<ActionResult> ForgotPassword(ForgotPasswordViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = await 
          _userManager.FindByNameOrEmailAsync(model.UsernameOrEmailAddress);

        if (user == null || !(await _userManager.IsEmailConfirmedAsync(user.Id)))
            {                 
                return View("ForgotPasswordConfirmation");
            }
        }
        else
        {
          return View(model);
        }
   }

You need to set the correct tenant.

If the username or email address is unique across tenants, inject IUnitOfWorkManager and do:

using (_unitOfWorkManager.Current.DisableFilter(AbpDataFilters.MayHaveTenant))
{
    var user = await _userManager.FindByNameOrEmailAsync(model.UsernameOrEmailAddress);
    // ...
}

If _unitOfWorkManager.Current is null, wrap the above code in:

using (var uow = _unitOfWorkManager.Begin())
{
    // Above code goes here

    uow.Complete();
}
