Hi. We tried the agent feature in the latest release and got a couple of questions. This might be a long thread so please let me know what could be the best way to communicate, and I will happy to share more. • There is no way to set log URL for an agent so on flyteconsole it is not possible to see log link. I think this is mainly because

core.TaskInfo

is not exposed to agent and

Status

call is transparent to agent. • It is not supported for an agent to already send back a result (resource) as part of

CreateTask

call. While this makes sense for many async tasks, it does not play well with synchronous tasks that can already return a result fairly quickly. The workaround we have now is sending back the result in

CreateTaskResponse.ResourceMeta

and then in

GetTask

call we just send the

ResourceMeta

back directly as

Resource

. Basically some byte array back and forth. • When

CreateTask

gRPC calls fails, the workflow (a single-tasked one in our test) does not fail and the task appears as queued forever (maybe there is a timeout eventually). And there is generally no way to signal a failure type (e.g. using gRPC error code) in any of the calls (Create/Get/Delete), if I understood it correctly. cc @glamorous-carpet-83516 whom I know has been working on this feature a lot.

This is great @steep-jackal-21573 - we should probably move this conversation to a doc?

re 1: we could add a log link in the resource, so you agent can return a log link re 2: I think sync plugin can address your issue. @damp-lion-88352 is working on it re 3: this is a known issue. I fixed it here. and it will show the grpc error message in flyteconsole. and yes, happy to learn more about your use case

Thank you for the quick answer. I will start a doc and share the link here.
