No decision found for key

Error message

No decision found for key: <decisionKey> and tenantId: <tenantId>.

What it means

Thrown when a decision is resolved by key and tenantId with fallback-to-default-tenant disabled and no Decision exists for that exact key+tenantId combination. The engine refuses to fall back, so the lookup fails outright.

Solutions

1. Enable fallbackToDefaultTenant in DmnEngineConfiguration (dmnEngineConfiguration.setFallbackToDefaultTenant(true)) or pass fallbackToDefaultTenant() on the builder so the default tenant can be used.
2. Correct the tenantId to the tenant under which the .dmn file was deployed.
3. Deploy the decision under the requested tenantId.
4. Verify existence with DmnRepositoryService.createDecisionQuery().decisionKey(key).tenantId(tenantId).count().

Example fix

// before
dmnEngine.executeDecision(new ExecuteDecisionBuilderImpl().decisionKey("risk").tenantId("acme"));
// after
dmnEngine.executeDecision(new ExecuteDecisionBuilderImpl().decisionKey("risk").tenantId("acme").fallbackToDefaultTenant());

boolean exists = dmnRepositoryService.createDecisionQuery().decisionKey(key).tenantId(tenantId).count() > 0;
boolean fallback = dmnEngine.getDmnEngineConfiguration().isFallbackToDefaultTenant();
if (!exists && !fallback) throw new IllegalStateException("Decision " + key + " not in tenant " + tenantId + " and fallback disabled");

try { dmnEngine.executeDecision(builder.decisionKey(key).tenantId(tenantId)); }
catch (FlowableObjectNotFoundException e) { dmnEngine.executeDecision(builder.decisionKey(key).tenantId(defaultTenant)); }

When it happens

Trigger: Executing a decision with decisionKey and tenantId set where isFallbackToDefaultTenant() is false (context and engine config) and findDecisionByKeyAndTenantId returns null.

Common situations: Decision deployed under a different tenant; tenantId spelled incorrectly; decision only in the default tenant while the caller passes an explicit tenant with fallback disabled; multi-tenant deployment mismatch after environment migration.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
