C# How to get exact error message from Logic App triggered by HttpRequest instead of default error m-CodePudding

I have a simple console application and it calls a Logic App by HttpRequest.

When the Logic App fails at any step I want to get exact the error message saying why it fails.

In the Logic App I can see the error.

Example: in the image, it fails at step 2 which it can't convert a string into an int. It's saying:

InvalidTemplate. Unable to process template language expressions in action 'Parse_JSON' inputs at line '0' and column '0': 'Required property 'content' expects a value but got null. Path ''.'.

which is what's I expect.

Here is my Logic App design:

But when I debug in a console application, it gives me a message "The server did not receive a response from an upstream server. Request tracking id 'some random Ids'." which is not very useful.

Here is my console application:

var obj = new
        {
            Age = "Twenty",
            Name = "James"
        };
        using (var client = new HttpClient())
        {
            var content = new StringContent(JsonConvert.SerializeObject(obj));
            content.Headers.ContentType.MediaType = "application/json";
            var response = await client.PostAsync(url, content);
            var errorMessage = await response.Content.ReadAsStringAsync();
            //errorMessage: {"error":{"code":"NoResponse","message":"The server did not receive a response from an upstream server. Request tracking id 'some random Ids'."}}
        }

So is there anyway to make the C# response return the error message in the step 2 of the Logic App?

What I expect is:

InvalidTemplate. Unable to process template language expressions in action 'Parse_JSON' inputs at line '0' and column '0': 'Required property 'content' expects a value but got null. Path ''.'.

Not:

{"error":{"code":"NoResponse","message":"The server did not receive a response from an upstream server. Request tracking id 'some random Ids'."}}

Thank you in advanced.

CodePudding user response：

You can use actions('<Your_Previous_Step>')['error'] in your case actions('Parse_JSON')['error'] doing so you can able to retrieve the error message of that particular action.

Here is my logic app

I'm testing this through postman. Below is the response I received in postman.

Make sure you set Configure run after options to make the flow work even after it gets failed.
