_userManager.ReplaceClaimAsync error Id = 414, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}" - asp.net-core

Question

In my controller asp.net core 6.0 I got this error when execute ReplaceClaimAsync:
Id = 414, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}"
var user11 = _userManager.FindByIdAsync(User.Id).Result;
user11.Email = user.Email;
var Result = _userManager.UpdateAsync(user11).Result;
if (!Result.Succeeded)
{
ModelState.AddModelError(Result.Errors.First().Code, Result.Errors.First().Description);
//throw new Exception(result.Errors.First().Description);
return BadRequest(ModelState);
}
var claimsOriginaux = _userManager.GetClaimsAsync(user11);
var claimOld = claimsOriginaux.Result.FirstOrDefault(r => r.Type == JwtClaimTypes.GivenName);
var claimNew = new Claim(JwtClaimTypes.GivenName, User.GivenName);
if (claimNew.Value != claimOld.Value)
{
var temp = _userManager.ReplaceClaimAsync(user11, claimOld, claimNew);
}
return NoContent(); //success
Any clue?

Answer 1

You are calling a bunch of async methods, and you are not using them the way you should.
You should await all async methods, instead of calling the .Result property.

Answer 2

Using await
var user11 = await _userManager.FindByIdAsync(User.Id);
user11.Email = user.Email;
var Result = await _userManager.UpdateAsync(user11);
if (!Result.Succeeded)
{
ModelState.AddModelError(Result.Errors.First().Code, Result.Errors.First().Description);
//throw new Exception(result.Errors.First().Description);
return BadRequest(ModelState);
}
var claimsOriginaux = await _userManager.GetClaimsAsync(user11);
var claimOld = claimsOriginaux.Result.FirstOrDefault(r => r.Type == JwtClaimTypes.GivenName);
var claimNew = new Claim(JwtClaimTypes.GivenName, User.GivenName);
if (claimNew.Value != claimOld.Value)
{
var temp = await _userManager.ReplaceClaimAsync(user11, claimOld, claimNew);
}
return NoContent(); //success
or
Using GetAwaiter()
var user11 = _userManager.FindByIdAsync(User.Id).GetAwaiter().GetResult();
user11.Email = user.Email;
var Result = _userManager.UpdateAsync(user11).GetAwaiter().GetResult();
if (!Result.Succeeded)
{
ModelState.AddModelError(Result.Errors.First().Code, Result.Errors.First().Description);
//throw new Exception(result.Errors.First().Description);
return BadRequest(ModelState);
}
var claimsOriginaux = _userManager.GetClaimsAsync(user11).GetAwaiter().GetResult();
var claimOld = claimsOriginaux.Result.FirstOrDefault(r => r.Type == JwtClaimTypes.GivenName);
var claimNew = new Claim(JwtClaimTypes.GivenName, User.GivenName);
if (claimNew.Value != claimOld.Value)
{
var temp = _userManager.ReplaceClaimAsync(user11, claimOld, claimNew).GetAwaiter().GetResult();
}
return NoContent(); //success
