Im having a problem with mender-deployment uploading artefacts to Minio storage. From the Mender web GUI Im seeing the following error.
“Artifact couldn’t be uploaded. reading artifact error: Payload: can not install Payload: .ext4: io: read/write on closed pipe… [Request ID: 9df1ee4e]”
mender-deployment log shows the following
mender-deployments@mender-server | time=“2020-03-11T11:12:28Z” level=error msg=“reading artifact error: Payload: can not install Payload: .ext4: io: read/write on closed pipe: Cannot parse artifact file” file=api_deployments.go func=“http.(*DeploymentsApiHandlers).newImageWithContext” line=330 request_id=e7ac735a-41b2-4185-be1b-cb36a370d0f2 user_id=8cfd8d07-####-####-####-############

Minio is a binary install on a separate server with external IP address and valid certificate. A user and group have been created on Minio for Mender to use. The policy for the group allows create permissions for mender artifact bucket and read and write permissions in the bucket.
The full Mender stack is installed with the exception of Minio and storage gateway, as minio is being treated like standard S3.
