During the operation of the docker full command, an error appears in the distribution logs:

ERRO[0137] error resolving descriptor in ServeBlob listener: frostfs: couldn't get object from tree: failed to get node by path: rpc error: code = Canceled desc = context canceled  environment=development go.version=go1.22.4 http.request.host="localhost:5000" http.request.id=d66d4248-74dc-4caf-8cb9-bdcfc62ca53c http.request.method=GET http.request.remoteaddr="127.0.0.1:46946" http.request.uri="/v2/redis/blobs/sha256:efc2b5ad9eec05befa54239d53feeae3569ccbef689aa5e5dbfc25da6c4df559" http.request.useragent="docker/26.0.0 go/go1.21.8 git-commit/8b79278 kernel/6.5.0-44-generic os/linux arch/amd64 UpstreamClient(Docker-Client/26.0.0 \\(linux\\))" instance.id=a523fc39-f7f4-4285-857d-9e9a2cbccb6c service=registry vars.digest="sha256:efc2b5ad9eec05befa54239d53feeae3569ccbef689aa5e5dbfc25da6c4df559" vars.name=redis version=v3.0.0-beta.1.m+unknown

At the same time, the request itself is completed successfully and there is no negative effect on the result of the work:

The error itself occurs due to the fact that the context is canceled from outside the frostfs driver code.

Steps to Reproduce (for bugs)

Pull an image from the Docker Pub (not necessarily this one, you can use any one)

$ docker pull redis:latest

We do all the actions to launch distribution:

2.1 Raising frostfs-aio

2.2 Creating a container

2.3 Add its id and the path to the wallet to the config file distribution: ./cmd/registry/config-dev-frostfs.yml

2.4 We are building distribution from the root of the project and launching

$ make binaries

$ ./bin/registry serve cmd/registry/config-dev-frostfs.yml

We put a tag on the image so that we can upload it to our registry

$ docker tag redis:latest localhost:5000/redis:latest

Push the image

$ docker push localhost:5000/redis:latest

Deleting the image from your computer (so that the pull is complete)

$ docker rmi redis:latest

$ docker rmi localhost:5000/redis:latest

We pool the image and observe an error in the logs

$ docker pull localhost:5000/redis:latest
