Invoking a global async method in code stage

KingSerok — Mon, 24 Jul 2023 13:38:00 GMT

Hello,

I developed an async method in my Blue Prism object's initial page (global code):

 static async Task<string> GetAuthenticationResponseAsync()
    {
       ...
    }

The method returns a string value.

Now, I need to invoke this method in the Blue Prism's code stage. How can I invoke an async method in the Blue Prism code stage?

I've tried this:

string responseData = await GetAuthenticationResponseAsync();

however, the compiler is complaining:

The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'.

I also tried:

responseData = GetAuthenticationResponseAsync().GetAwaiter().GetResult();

This resolved the compiler error, however, when I run the action (code stage), Blue Prism is permanently stuck on the code stage, and I have no option but to terminate Blue Prism via task manager.

Is there a way that I could invoke the async method through the code stage?

Thanks!

Does this link to a previous thread help you any? It looks like there is an Output() method at the end of the suggested code.

For Async function

Here is the best solution for BP code stage I got implemented.

var result = Task.Run(async () => await GetAccessToken()).Result;
