SnapLogic Errors: Return custom payload and fail pipeline

hey omair,

Have you tried the Exit snap? It allows you to set an error message that can be returned to the user.

If you call that via a triggered task, then you’ll get this kind of response.

[
      {
      "failure" : "Pipeline execution failed while waiting for output",
      "reason" : "Snap errors: {ruuid=52e99318640a9a03d8681d0d_9b3dd03a-dde2-43e8-a0ba-fd58239c2a5d, reason=Number of input documents received is more than 0, label=Exit, resolution=Try passing less than or equal to 0 input documents, failure=Beep Boop! Failure!}",
      "resolution" : "Fix the reported errors"
    }
]

You’d still have to extract it from the reason String, so not the most user friendly way.

You could also do something like this:

Where the mapper returns the output before the exit snap is invoked using a sleep in a Script snap. This will return a response like

[
    {
        "error": "Beep Boop! Failure!"
    }
]

Which is easier to deal with.

This isn’t the most elegant approach since there is a race condition between when the mapper’s output is written out and when the exit snap processes the document from its input stream.
