Solution à tester ?
@markdingram: something like this worked for us
$ kubectl get secret sh.helm.release.v1.xxx.v123 -o json > secret.orig.json
$ cat secret.orig.json | jq -r '.data.release' | base64 -d | base64 -d | gzip -d > secret.json
$ vi secret.json <- change status to "deployed"
$ cat secret.json | gzip | base64 | base64 > secret.encoded
$ jq -r '.data.release = $input' secret.orig.json --rawfile input secret.encoded > secret.new.json
$ kubectl apply -f secret.new.json
