Build fails when tyring to use a custom source to image (s2i) on Openshift

Issue

The starting point is as follows:
- A template referencing a customized s2i existing in a Git repository
- This custom s2i image starts from the s2i-base-rhel7 image

# oc create -f my-s2i-app.yaml
# oc new-app --template=my-s2i-app

Build fails with the following error:

# oc logs -f my-s2i-app-1-build 
error: build error: image "registry.access.redhat.com/rhscl/s2i-base-rhel7@sha256:5ee732130640c99a89c50bcbe9c7ad2552234c1828f57f32cee59e44957a2446" must specify a user that is numeric and within the range of allowed users

The template has a BuildConfig definition like the following:

- apiVersion: v1
  kind: BuildConfig
  metadata:
    annotations:
      description: Defines how to build the application
    name: ${APPLICATION_NAME}
  spec:
    output:
      to:
        kind: ImageStreamTag
        name: ${APPLICATION_NAME}:latest
    source:
      contextDir: ""
      git:
        ref: "master"
        uri: "http://<git-repository-url>/my-s2i-definition.git"
      type: Git
    strategy:
      sourceStrategy:
        from:
          kind: ImageStreamTag
          name: s2i-base-rhel7:latest
      type: Source
    triggers:
    - type: ImageChange
