Local images are failing for tasks in Openshift pipelines 1.11

I have following task definition (simplified):

apiVersion: tekton.dev/v1beta1kind: Taskmetadata:  name: my-task  namespace: mynamespace  params:    - default: 'image-registry.openshift-image-registry.svc:5000/mynamespace/mytaskimage'      description: image used to execute this task      name: task-image      type: string  steps:    - command:        - ./runscript.sh      image: $(params.task-image)      name: run-script      resources: {}

This task was working fine in Openshift pipelines 1.10.6 but is failing in 1.11.1

It is failing with error:

Generated from TaskRunbuild step "step-run-script" is pending with reason "rpc error: code = Unknown desc = reading manifest latest in image-registry.openshift-image-registry.svc:5000/mynamespace/mytaskimage: manifest unknown"

Any hints how to use local images in task in 1.11+ pipelines?The task image is in the same namespace.
