Hi everyone, I am pretty new to Mender so would like some help with this error. Basically my setup is

A Ubuntu 18.04 device with a mender client.  
A hosted mender server.

I am trying to do application updates only using a Docker image that is pulled from AWS ECR. A ‘hello-world’ docker image is stored on my AWS ECR and I use the amazon-ecr-credential-helper for authentication. But when I try to create the artifact I get the following error:

./docker-artifact-gen -n ${ARTIFACT\_NAME} -t ${DEVICE\_TYPE} -o ${OUTPUT\_PATH} ${DOCKER\_IMAGES}  
latest: Pulling from hello-world  
Digest: sha256:1b26826f602946860c27xxxxxxxxxxx  
Status: Image is up to date for [9972xxxxxxx.dkr.ecr.eu-central-1.amazonaws.com/hello-world:latest](http://9972xxxxxxx.dkr.ecr.eu-central-1.amazonaws.com/hello-world:latest)  
[9972xxxxxxxx.dkr.ecr.eu-central-1.amazonaws.com/hello-world:latest](http://9972xxxxxxxx.dkr.ecr.eu-central-1.amazonaws.com/hello-world:latest)  
writeArtifactV3: writing header: writer: error writing header: writer: can not store header-info

Any clue what is going on ?

Hey @w.cheema

Do you have the possibility to recompile mender-artifact with [this patch](https://github.com/mendersoftware/mender-artifact/pull/347/files), and then retry? Unfortunately the real error message is hidden, so we cannot see why it failed.

If you have the Go compiler installed, it should be a simple matter of cloning the repository, applying that patch, and running `make`. Then make sure your `PATH` points to that binary.

@kacf thanks for the help/patch but (un)fortunately the error went away and I cannot recreate it. I did too many things and have no idea what solved it and what was casing it.
