No deployment id provided

Error message

No deployment id provided

What it means

BaseDmnDeploymentResourceDataResource.getDmnDeploymentResourceData throws FlowableIllegalArgumentException("No deployment id provided") when the deploymentId parameter is null. This endpoint fetches a deployment resource by NAME, and both deploymentId and resourceName are mandatory; validation happens before any repository query.

Solutions

1. Supply the deployment id in the URL path; obtain it via GET /dmn-repository/deployments if unknown.
2. Fix URL building code so null/empty ids are caught before the request is sent.
3. Check controller mappings to ensure the deploymentId path variable is correctly bound.

Example fix

// before
String url = base + "/dmn-repository/deployments/" + deploymentId + "/resource-data/" + name; // deploymentId null
// after
Objects.requireNonNull(deploymentId, "deploymentId required");
String url = base + "/dmn-repository/deployments/" + deploymentId + "/resource-data/" + name;

if (deploymentId == null || deploymentId.isEmpty()) throw new IllegalArgumentException("deploymentId is required");

When it happens

Trigger: GET /dmn-repository/deployments/{deploymentId}/resource-data/{resourceName} with the {deploymentId} path variable null/empty, e.g. an empty interpolated variable in a generated URL or a misbound controller path variable.

Common situations: Template-generated URLs where the deploymentId variable was empty; framework routing that matched a shorter path pattern; client code passing null because a previous lookup failed silently.
