Change:
// FlattenListVisitor flattens any objects that runtime.ExtractList recognizes as a list // - has an "Items" public field that is a slice of runtime.Objects or objects satisfying <del> // that interface - into multiple Infos. An error on any sub item (for instance, if a List // contains an object that does not have a registered client or resource) will terminate // the visit. // TODO: allow errors to be aggregated? </del> <ins> // that interface - into multiple Infos. Returns nil in the case of no errors. // When an error is hit on sub items (for instance, if a List contains an object that does // not have a registered client or resource), returns an aggregate error. </ins> type FlattenListVisitor struct { visitor Visitor typer   runtime.ObjectTyper

Discussion:
What happened: When using a yaml file for input, silently fails at the first missing resource, not returning any further results. What you expected to happen: Searching with cli arguments properly ignores missing resources and continues the query, eg: Would expect similar results with a file input, eg: How to reproduce it (as minimally and precisely as possible): With an input file of : the command fails at apparently the first missing resource: Note: that rearranging the inputs in (so that the missing resource is last) produces the "expected" output: Anything else we need to know?: Environment: Kubernetes version (use ):Cloud provider or hardware configuration: local OS (e.g: ): fedora 30 Kernel (e.g. ): Install tools: Network plugin and version (if this is a network-related bug): Others: x-ref:

Got around to reproducing it and can confirm that I'm getting the same behavior. I'm looking into fixing it now
thanks, any updates on this?
I've learned that in the case of a fake entry, kubectl stops sending API get requests altogether. Learned by running kubectl get -f --ignore-not-found --v=10, the result is shown below. Till now I've been looking into the cobra command framework but now I'm trying to find out where kubectl is making these API calls from(working on finding out where this connection is happening from Slack+debugging, I've asked a more detailed question here ). <img width="1440" alt="Screen Shot 2019-08-12 at 4 13 41 PM" src="https://user-"
that's an interesting find, definitely helpful. When I looked into this I got to the section of get's main run function, and it seems like it should be continuing on any errors (see ) but maybe the ResourceBuilder is actually stopping when it hits a 404?
This behavior comes from where the not found errors are being ignored and where the input list is flattened. Errors are ignored here: While flattening occurs here: As the visitor iterates through the objects in the list if an error occurs, such as not found, it will stop iterating over the objects in the list and return that not found error. The logic will then ignore it and continue.

Any objects that came before the not found object in the list will have been visited and will then be included in the output. To make the behavior consistent between the two ways of getting the set of objects, the would need to be updated to support filtering errors.
Just submitted a PR adding that functionality to the FlattenListVisitor. The behavior is now consistent between the two methods.
