xUnit: Can't assert exceptions

Hello, there! I want to compare exception types, but I'm getting error. Here's my code:

        var exception = await Assert.ThrowsAsync<ArgumentException>(() => _endpoint.GetReport("1.1.1.1", null));
        Assert.Equal("Api key shouldn't be empty.", exception.Message);

        var exception = await Assert.ThrowsAsync<ArgumentException>(() => _endpoint.GetReport("1.1.1.1", null));
        Assert.Equal("Api key shouldn't be empty.", exception.Message);

Here's an error:

System.ArgumentException: Api key shouldn't be empty.

System.ArgumentException
Api key shouldn't be empty.

System.ArgumentException: Api key shouldn't be empty.

System.ArgumentException
Api key shouldn't be empty.

Here's part of code which I want to test:

protected string ApiKey
    {
        get => _apiKey;
        init
        {
            if (string.IsNullOrWhiteSpace(value))
            {
                throw new ArgumentException("Api key shouldn't be empty.");
            }

            _apiKey = value;
        }
    }

protected string ApiKey
    {
        get => _apiKey;
        init
        {
            if (string.IsNullOrWhiteSpace(value))
            {
                throw new ArgumentException("Api key shouldn't be empty.");
            }

            _apiKey = value;
        }
    }

Can you show the code for _endpoint.GetReport?

    public async Task<IpAnalysisResult> GetReport(string ipAddress, CancellationToken? cancellationToken)
    {
        var request = new RestRequest($"/{ipAddress}").AddHeader("x-apikey", ApiKey);

        RestResponse restResponse;

        if (cancellationToken is not null)
        {
            restResponse = await Client.ExecuteGetAsync(request, cancellationToken.Value);
        }
        else
        {
            restResponse = await Client.ExecuteGetAsync(request);
        }

        if (restResponse is { IsSuccessful: true})
        {
            var resultJsonDocument = JsonDocument.Parse(restResponse.Content!);
            var result = resultJsonDocument.RootElement.GetProperty("data").Deserialize<IpAnalysisResult>(_jsonSerializerOptions)!;
            return result;
        }

        HandleError(restResponse.Content!);
        return new IpAnalysisResult();
    }

    public async Task<IpAnalysisResult> GetReport(string ipAddress, CancellationToken? cancellationToken)
    {
        var request = new RestRequest($"/{ipAddress}").AddHeader("x-apikey", ApiKey);

        RestResponse restResponse;

        if (cancellationToken is not null)
        {
            restResponse = await Client.ExecuteGetAsync(request, cancellationToken.Value);
        }
        else
        {
            restResponse = await Client.ExecuteGetAsync(request);
        }

        if (restResponse is { IsSuccessful: true})
        {
            var resultJsonDocument = JsonDocument.Parse(restResponse.Content!);
            var result = resultJsonDocument.RootElement.GetProperty("data").Deserialize<IpAnalysisResult>(_jsonSerializerOptions)!;
            return result;
        }

        HandleError(restResponse.Content!);
        return new IpAnalysisResult();
    }

You're not initializing ApiKey in that method though, it seems like it's already initialized in earlier code

yep, and I realised that I should created an Endpoint class in test, not in constructor, thanks!
