Query failed: many to many matching not allowed

[Anaka]

HI,

I have a query like below:

container_memory_working_set_bytes{cluster="$cluster", container="my-container", namespace="my-namespace"} / on (pod) kube_pod_container_resource_requests{cluster="$cluster",namespace="my-namespace",container="my-container",resource="memory"}

this query failed and report an error like below, but per my understanding, they have different 'Pod' labels，

Has anyone dealt with this specific error and can you recommend something?
