Customer is planning to upgrade the OCP cluster from 4.13.28 to the latest OCP version.

Using upgrade path https://access.redhat.com/labs/ocpupgradegraph/update_path/ , we can get the OCP 4.14.x versions available for upgrade with some risks.

However , when we run below commands/script, we are getting only 4.13.29 and 4.13.30 versions available for upgrade :
~~~
# export CURRENT_VERSION=4.13.28
# export CHANNEL_NAME=eus-4.14
# curl -sH 'Accept:application/json' "https://api.openshift.com/api/upgrades_info/v1/graph?channel=${CHANNEL_NAME}" | jq -r --arg CURRENT_VERSION "${CURRENT_VERSION}" '. as $graph | $graph.nodes | map(.version=='\"$CURRENT_VERSION\"') | index(true) as $orig | $graph.edges | map(select(.[0] == $orig)[1]) | map($graph.nodes[.].version) | sort_by(.)'
[
  "4.13.29",
  "4.13.30"
]
~~~
Available 4.14.x versions to upgrade the cluster from version 4.13.28 are not getting updated here.

1. Set the environment variables :
$ export CURRENT_VERSION=4.13.28
$ export CHANNEL_NAME=eus-4.14
2. Run below shift :
$ curl -sH 'Accept:application/json' "https://api.openshift.com/api/upgrades_info/v1/graph?channel=${CHANNEL_NAME}" | jq -r --arg CURRENT_VERSION "${CURRENT_VERSION}" '. as $graph | $graph.nodes | map(.version=='\"$CURRENT_VERSION\"') | index(true) as $orig | $graph.edges | map(select(.[0] == $orig)[1]) | map($graph.nodes[.].version) | sort_by(.)'
4. Check available versions to upgrade the OCP cluster
    

Script is showing only two versions 4.13.29 and 4.13.30 available for upgrade from version 4.13.28

Script should also print the available 4.14.x versions for upgrade from version 4.13.28
