Binary output - error pipeline - custom http codes

There is a requirement for the following: Error pipeline for an ultra pipeline which responses with custom HTTP code, e.g. 500. Why: …The third party API caller shall receive a proper HTTP code...

    Using a mapper and assuming your input text is at the key $text you can use the following expression to achieve your goal:

    $text.split("").reverse().reduce((accum, cur) => (accum.length - accum.split("+").length +1) % 3 == 0 ? accum + "+" + cur: accum + cur).split("").reverse().join("")

Yes it is possible, however, if you are trying that with the Document to Binary snap make sure the data on the input has the $content field otherwise that snap will fail because it requires the content field. You can also output custom message from the error pipeline, you can do something like this:

  1. Drop a Mapper snap
  2. Change the output view to binary type in the Views tab
  3. Write the below expression ( this is only a sample, it doesn’t have to be like this )

    If there is an error in your pipeline, the error pipeline will output this error message if configured properly.

Thanks again.
However, the answer does not refer to the question.
I have edited the initial post again with more information.

    Hi @Szymon,

    I created a sample ultra pipeline with an error pipeline and you actually can’t have an open binary output view on the error pipeline, it has to be document output view. However, you can still manipulate the status code for the error message.
    This is a simple error pipeline that outputs the error message if there are any errors from the main pipeline.

    If you call this API and if the pipeline has an error, for example you’ll receive the following response based on the configuration of the mapper snap in the error pipeline:


    You can notice that the status in the response corresponds to the status in the Mapper snap.
