Unable to determine endpoint type for ppc64le agent

[disprosium8]

Running portainer-ce on amd64 and agent 1.6.0 on ppc64le using portainer/agent:linux-ppc64le

When trying to register Agent as new Endpoint via webUI:

-ce log:
2020/09/16 17:07:13 http error: Unable to get endpoint type (err=Agent Platform Header is missing) (code=500)

Agent debug run:
docker run -ti -p 9001:9001 --network=portainer_agent_network -e AGENT_CLUSTER_ADDR=<ip> --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock --mount type=bind,src=//var/lib/docker/volumes,dst=/var/lib/docker/volumes portainer/agent:linux-ppc64le --platform=ppc64le portainer/agent:linux-ppc64le

Also tried:
docker service create --name portainer_agent --network portainer_agent_network --publish mode=host,target=9001,published=9001 --mode global --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock --mount type=bind,src=//var/lib/docker/volumes,dst=/var/lib/docker/volumes --no-resolve-image portainer/agent:linux-ppc64le

Without --no-resolve-image the service will report unsupported architecture and not start.

Probable issue is that Architecture is set to amd64 in ppc64le image?

$ docker inspect portainer/agent:linux-ppc64le
...
        "Architecture": "amd64",
        "Os": "linux",
        "Size": 13516934,
...

Many other amd64 agent endpoints have registered and are usable using the same method at the same instance.

Am also running into this

From ppc64le-host:

$ docker pull portainer/agent
Using default tag: latest
latest: Pulling from portainer/agent
no matching manifest for linux/ppc64le in the manifest list entries

From amd64-host:

$ docker pull portainer/agent:linux-ppc64le >/dev/null && docker manifest inspect portainer/agent:linux-ppc64le --verbose | grep architecture
                        "architecture": "amd64",

Confirming that this is till an issue:

root@dev5p:~# docker pull portainer/agent:latest
latest: Pulling from portainer/agent
no matching manifest for linux/ppc64le in the manifest list entries

However, specifying a version works:

root@dev5p:~# docker pull portainer/agent:2.19.1

This is also visible on docker-hub by the linux/ppc64le-tag missing on the latest-tag, but being present on the versioned tag:
