blazor http generic client what is proper way to handle nulable type like this?

I build some blazor app

and i want to have HttpGet like

person? x = await _httpClient.Get<person?>("url");

So from api if i return person then i want x to be it value, if from api i return NULL want to x be NULL

How to do this properly?

i have some httpclient with get like for example

public async Task<T> Get<T>(string uri, int timeOut = 100){                   using var response = await _httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Get, uri), linkedCts.Token);        return await response.Content.ReadFromJsonAsync<T>();    }}

but the compilator on this response.Content.ReadFromJsonAsync<T>() says that possible null return

But still if I return NULL from api then it throwsThe input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. Path: $ | LineNumber: 0 | BytePositionInLine: 0.'

so does i need it to change to be of Task<T?> so it may return null? what is right path here?

what is best approach for this ? or am I missing something and this is not right way ?

Thank You and regards!
