Pipeline failing with gitlab runner kubernetes and K8S API server v1.17.4 (BadRequest)

I’ve a lot of gitlab runners (v12.9, v12.8 and v12.2) with executor kubernetes. I updated my K8S API Server (from v1.17.2 to v1.17.4) in last weekend and all pipelines are presenting the error bellow:

Error from server (BadRequest): a container name must be specified for pod runner-sdpj7eum-project-10427-concurrent-0n79zz, choose one of: [build helper]

Is there a specific parameter to set pod names on kubernetes or gitlab runner don’t support k8s API server v1.17.4?
