Data Actions API versioning fails with 422 on atomic PUT

Hi all. Java HTTP client returns 422 Unprocessable Entity pushing VERSION_TAG matrix to the action versioning endpoint. Payload includes ACTION_ID references and diff summary directives. SCHEMA_VALIDATION rejects before ATOMIC_PUT. RETENTION_LIMITS fine, three tags. SEMANTIC_VERSION_INCREMENT trigger fires. AUDIT_LOGS blank. Response dumps version_schema_mismatch.

{ "actionId": "8a1b2c3d-4e5f-6789-0abc-def123456789", "versionTag": "v2.1.0", "backwardCompatible": true }
2 
{
 "actionId": "8a1b2c3d-4e5f-6789-0abc-def123456789",
 "versionNumber": 2,
 "complianceMetadata": {
 "retentionPolicy": "MiFID_II_ARCHIVE",
 "legalHold": true,
 "securePauseDirective": false
 }
}

Audit requirements dictate that all Data Action version updates must include explicit retention parameters. The 422 response triggers when the payload omits the mandatory compliance metadata block. Dodd-Frank 15c3-1 and MiFID II Article 16 both require immutable version tracking for any policy modification. The endpoint rejects diff summary directives because they bypass the legal hold validation. Replace the nested array with the structure above. Set legalHold to true if the action modifies any recording retention rules.

Check the gateway logs. You’ll see the schema validator drop the request immediately.
[ERROR] validation.service: field 'complianceMetadata' is required for version bump ...
Just a fragment. The rest gets truncated by the SIEM filter.

Keep the Content-Type header strict. The Java client sometimes appends charset parameters that break the parser. Retention must default to 2555 days for MiFID II archives. The secure pause directive belongs in the WFM quality module, not here. That’s for PCI masking on live channels anyway. Leave it out. Version bumps fail when the audit trail isn’t explicitly declared.
