Additional context
it seems the fault lies at io.kubernetes.client.openapi.apis.AppsV1Api:9231, it sets Content-Type header value to application/json where it should be application/strategic-merge-patch+json according to docs here
This has a workaround but that shouldnt be the case
PatchUtils.patch(
V1Deployment.class,
() -> client.buildCall(
null,
String.format(
"/apis/apps/v1/namespaces/%s/deployments/%s",
namespaceParam,
deploymentParam),
"PATCH",
new ArrayList<>(),
new ArrayList<>(),
new V1Patch(PATCH_JSON.formatted(timeNow)),
HEADERS,
new HashMap<>(),
new HashMap<>(),
new String[] {"BearerToken"},
null),
"application/strategic-merge-patch+json");
