Kubernetes apply command produces 'wrong encoding error'

Question

I'm trying to execute:

microk8s kubectl apply -f  deployment.yaml

and I am always getting:

error: string field contains invalid UTF-8

No matter which file and string as a file path parameter I'm trying to use. Even if I execute:

microk8s kubectl apply -f  blablabla

Result is the same.

UPD: I resolved the problem by restarting microk8s service. After restart everything is fine, but I still have no idea what it was.

share you yaml file that you are trying to apply, add more details to question — Harsh Manvar, Aug 09 '21 at 19:09
I repeat microk8s kubectl apply -f resulting as error: string field contains invalid UTF-8 — Сергей Коновалов, Aug 09 '21 at 20:06
@СергейКоновалов , the error you are telling is most likely due to your input file to `kubectl apply -f ` command. its imortant you share your input file and its content for further help. — P...., Aug 09 '21 at 20:46
what OS do you use? May be it should be `microk8s.kubectl`. Anyway there is a way to raise verbosity and find out some details e.g: `microk8s.kubectl -v=9 get no` All the best — Alex A, Aug 09 '21 at 18:32
this is not an answer, its more like a comment. Suggesting to move it to comment section. — P...., Aug 09 '21 at 19:08
@СергейКоновалов, please post your solution as an answer. — Mikołaj Głodziak, Aug 10 '21 at 06:55

This is not a wrong format in the manifest, instead, it's a corrupted cache in $HOME/.kube/

try to delete the cache:

rm -rf $HOME/.kube/http-cache

rm -rf $HOME/.kube/cache
