Could not find a DMN deployment with id

Error message

Could not find a DMN deployment with id '<deploymentId>

What it means

GET /dmn-repository/deployments/{deploymentId} queries DmnDeploymentQuery for the id; when no deployment matches, the handler throws FlowableObjectNotFoundException so the caller receives a 404 instead of an empty response. The message confirms the deployment id was not found in the DMN engine repository.

Solutions

1. List deployments (GET /dmn-repository/deployments) to confirm the id exists.
2. Fix the deployment id (check for typos or using a decision/definition id instead).
3. Verify you are querying the correct Flowable DMN service instance and database.
4. If it was deleted, redeploy the DMN model and use the new deployment id.

Example fix

// before
const dep = await get('/dmn-repository/deployments/' + decisionTableId);
// after
const table = await get('/dmn-repository/decision-tables/' + decisionTableId);
const dep = await get('/dmn-repository/deployments/' + table.deploymentId);

const list = await get('/dmn-repository/deployments');
if (!list.data.some(d => d.id === deploymentId)) throw new Error('unknown deployment id: ' + deploymentId);

function isKnownDeployment(dep) { return typeof dep === 'object' && dep !== null && typeof dep.id === 'string'; }

try { return await getDeployment(id); }
catch (e) { if (e.status === 404) return null; throw e; }

When it happens

Trigger: Requesting a deployment id that was never created, was deleted via DELETE, belongs to a different Flowable app/service, or contains a typo/trailing whitespace.

Common situations: Stale ids cached in a client UI after redeployment cleanup, pointing a DMN client at the wrong service (process engine deployments vs DMN deployments), environments (test vs prod) with different databases, or id confusion between deployment and decision-table ids.

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.
