Error: validation_failed [shard_allocation_matrix.invalid_format]
at client.SendOptimizationPayload() line 87
We’ve been trying to push index optimization directives through the Genesys Cloud Interaction Search endpoint, but the cluster keeps rejecting the JSON body. The request hits /api/v2/interactions/search/optimization/shards and immediately bounces back with that 422. I’ve checked the schema docs and the index ID references look correct, but something’s tripping up the rebalance strategy directive. Here’s what we’re sending:
{
“indexId”: “prod-interactions-2024”,
“shardAllocationMatrix”: {
“primary”: 5,
“replica”: 2,
“rebalanceStrategy”: “depth_first”
},
“validationChecks”: {
“diskUsageThreshold”: 0.85,
“maxQueryLatencyMs”: 450
}
}
The Go client handles the atomic PUT fine, but the format verification step on the server side seems to choke on the matrix values. We added a disk usage checking pipeline locally to simulate node capacity limits before sending, yet the API still throws the same validation error. It’s probably a type mismatch somewhere in the JSON marshaling, but the logs don’t specify which field failed. The callback handler for external monitoring never fires since the request drops immediately. Query latency verification passes on our end, so the payload structure should be fine. Maybe the shard distribution needs a specific UUID format instead of integers? We’ve tried swapping the replica count to a string, but that just breaks the schema validator harder. The audit log generator keeps recording failed optimization attempts, which messes up our compliance tracking. Anyone else hit this wall when pushing shard optimization payloads? The documentation doesn’t mention automatic replication triggers failing on PUT requests either. Just stuck on the exact format the search engine expects for the allocation matrix.
