Exception in .Net MAUI App: "System.ObjectDisposedException: Cannot access a closed Stream" on Andro
I am currently developing a .Net MAUI application where I am making an HTTP call. The peculiar issue I am facing is that the function works perfectly fine on Windows, but when I attempt to execute it on my Local Android Device, it throws an exception after line var response = await client.PostAsync(url, content);
> "System.ObjectDisposedException: Cannot access a closed Stream."
```
public async static Task InsertParts(IEnumerable<PartDTO> partsToReport)
{
using (HttpClient client = GetClient())
{
AddAuthorizationHeader(client);
string url = $"{Url}/endpoint";
string jsonData = JsonSerializer.Serialize(partsToReport);
HttpContent content = new StringContent(jsonData, Encoding.UTF8, "application/json");
var response = await client.PostAsync(url, content);
if (!(response.IsSuccessStatusCode))
{
throw new Exception($"Failed to insert parts: {response.ReasonPhrase}");
}
}
}
```
```
public static HttpClient GetClient()
{
#if DEBUG
HttpClientHandler insecureHandler = new HttpClientHandler();
insecureHandler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;
return new HttpClient(insecureHandler);
#else
return new HttpClient();
#endif
}
```
GET and DELETE works on both platforms
The Post operation like this works on both platforms
> HttpResponseMessage response = await client.PostAsync($"{Url}/inventory/{id}/{destination}", null);
but when I try to put content in the request then it does not work on android but works in Windows.
- I found the answer I don't know how it works but I removed this single line from my asp.net APIapp Program.cs file "//app.UseHttpsRedirection();" After removing that it worked. one of the answers in this https://stackoverflow.com/questions/71047509/trust-anchor-for-certification-path-not-found-in-a-net-maui-project-trying-t/71196389#71196389 got my solution but it was just a hunch for me
