I have a PR up to send custom_info from the Flyte agents back via GetTask at https://github.com/flyteorg/flytekit/pull/2426 However, I don't think that it's actually being recorded anywhere inside flyteadmin. API calls have

custom:null

. I only took a quick look and have some ideas on where that might need to be plumbed in if anyone could have a look / leave comments. I just wrote some quick notes at https://github.com/flyteorg/flyte/pull/5391/files
