Migration to GenericKafkaListener failed if strimzi-operator was upgraded from 0.19.0=>0.20.1 (crd folder move)

Describe the bug Migration to GenericKafkaListener failed if strimzi-operator was upgraded from 0.19.0=>0.20.1=>0.21.1

Error: UPGRADE FAILED: release kafka-test failed, and has been rolled back due to atomic being set: cannot patch "test" with kind Kafka: Kafka.kafka.strimzi.io "test" is invalid: spec.kafka.listeners: Invalid value: "array": spec.kafka.listeners in body must be of type object: "array"

script returned exit code 1

To Reproduce Steps to reproduce the behavior:

1. install strimzi 0.19.0
2. upgrade to 0.20.1, than 0.21.1 using hotfix script from https://github.com/strimzi/strimzi-kafka-operator/issues/3877#issuecomment-832750622
3. try to switch to GenericKafkaListener listeners format
4. See error

Error: UPGRADE FAILED: release kafka-test failed, and has been rolled back due to atomic being set: cannot patch "test" with kind Kafka: Kafka.kafka.strimzi.io "test" is invalid: spec.kafka.listeners: Invalid value: "array": spec.kafka.listeners in body must be of type object: "array"

Expected behavior Kafka should switched to GenericKafkaListener listeners format (array)

Environment (please complete the following information):

• Strimzi version: [0.21.1]
• Installation method: [Helm chart]
• Kubernetes cluster: [1.20]
• Infrastructure: [AKS]

Additional context I see your comment https://github.com/strimzi/strimzi-kafka-operator/issues/3727#issuecomment-704386494. But unfortunately I have no idea how to apply crd from 0.21.1 release now. Have no idea why helm did’t do this. By the way fresh install from 0.21.1 release works as expected.

I’ve applied them manually via next snippet but got same error:

VERSION=0.21.1
RELEASE_FOLDER="$VERSION"

helm repo add strimzi http://strimzi.io/charts/
helm repo update
[ -d "$RELEASE_FOLDER" ] && rm -rf "$RELEASE_FOLDER"
helm pull strimzi/strimzi-kafka-operator --version "$VERSION" -d ./\
  --untar \
  --untardir "$RELEASE_FOLDER"

kubectl diff \
  -f "$VERSION/strimzi-kafka-operator/crds" \

read -p "Are you sure? " -n 1 -r
if [[ $REPLY =~ ^[Yy]$ ]]
then
  kubectl replace \
    --validate=false \
    -f "$VERSION/strimzi-kafka-operator/crds"
fi
