I'm trying to send a POST request with body from a frontend client to an ASP.NET (.NET 7.0) server (code below).
const URL = API_LINK + `/task-types`
await axios({
method: 'POST',
url: URL,
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
Authorization: `Bearer ${this.token}`,
},
data: JSON.stringify({
name: task.name,
description: task.description,
deactivated: task.deactivated,
}),
})
.then(res => console.log(res))
.catch(err => console.log(err))
[HttpPost]
public async Task<IActionResult> Create([FromBody] CreateTaskTypeCommand command)
{
await _mediator.Send(command);
return Ok();
}
On the backend side, it throws a ConnectionResetException. I don't know how to solve this and I haven't found a suitable solution to this problem on the internet.
Below is information from the log:

I tried to ignore this exception, but it didn't help.
I found the problem. In the html file, the button had the "submit" type (the fault of mindless copying and pasting of code fragments). As a result, it could not send a query to the server, and if it somehow managed to read the body on the backand side, it lost the connection.
