Summarising a chat with Kairo:

  • API results should be designed with the user in mind.
  • Case-handling of different results should be as easy as possible.
  • The user shouldn't need parse strings to make decisions.
  • If the user generally doesn't care for the difference between certain response types, or doesn't handle them differently, it might be okay to summarise those response type.
  • For now we stick to the existing response types coming and forward them mostly as they come from celery/worker.

Maybe we can consider some simplifications, if they don't disrupt existing clients:

  • Exclude redundant status field from task result.
  • Only mandate task results with message field for SUCCESS, ERROR, FAILURE state responses, and do not add them if they are missing in any of the other state responses.
  • Consolidate message and error fields for ERROR and FAILURE.
  • For ERROR the message could be a combination of what's currently in both fields, and error could be omitted.
  • For FAILURE the message could be the exception message, and error could be omitted or show the exception type.

Fix documentation about the type of task result in the
`/api/v1/tasks`.

The type was moved to `Dict[str, Any]`

It adds more consistency on task result in the API.
Verifying the `message` and `status` and `error` (in case of FAILURE)

I think the changes are okay. Feel free to address the two inline comments or not.

Regarding our chat:

  • Only mandate task results with message field for SUCCESS, ERROR, FAILURE state responses, and do not add them if they are missing in any of the other state responses.
  • Consolidate message and error fields for ERROR and FAILURE.
  • For ERROR the message could be a combination of what's currently in both fields, and error could be omitted.
  • For FAILURE the message could be the exception message, and error could be omitted or show the exception type.

Did you consider any of those? I suppose they are improvements that should be done in the worker first.

task_result = {"message": str(task.result)}
elif task_state == TaskState.SUCCESS and not task_result.get(
task_result = {
"message": f"Task failure: {str(task.result)}",

nit: IMO you can omit "Task failure: ". The info is redundant with the state.

"error": {
"type": "string",
"title": "Error",
"description": "If the task status result is `False` shows an error message"

Is this API user facing documentation? They don't know about task status, right?

Yes, most of them are how the RSTUF Worker sends the task result, not in the API.
We should file issues to do there, as a polishing result.

I noticed also that removing status from result is a breaking change for the CLI :)
I mean, we will need changes there.

Damn. I guess it's also okay to leave it, and ignoring it in the cli first?

Yes, I will revert it and file issues so we can do it without breaking operability.
