No decision execution id provided

Error message

No decision execution id provided

What it means

Thrown by getExecutionAuditData when the decisionExecutionId path/parameter supplied to the audit-data endpoint is null. The endpoint needs an id to look up and stream the stored execution JSON. It is rejected before any database access.

Solutions

1. Provide a non-null decisionExecutionId in the URL path before calling the endpoint
2. Build the URL from a validated variable rather than string concatenation that can yield an empty segment
3. Fetch a valid id from the historic-decision-executions list endpoint if unknown

Example fix

// before
String url = "/dmn-history/historic-decision-executions/" + id; // id == null
// after
Objects.requireNonNull(id, "decisionExecutionId must be set");
String url = "/dmn-history/historic-decision-executions/" + id;

if (decisionExecutionId == null || decisionExecutionId.isEmpty()) {
    throw new IllegalArgumentException("decisionExecutionId must be provided");
}

boolean hasId = id != null && !id.trim().isEmpty();

try {
    audit = client.getExecutionAuditData(id);
} catch (HttpClientErrorException e) {
    if (e.getResponseBodyAsString().contains("No decision execution id provided")) {
        throw new IllegalArgumentException("audit-data call requires an id", e);
    }
    throw e;
}

When it happens

Trigger: GET /dmn-history/historic-decision-executions/{decisionExecutionId}/audit-data (or similar) where the id path variable is empty/null after routing.

Common situations: Client building the URL without substituting the id placeholder; a proxy/gateway stripping an empty path segment; programmatic invocation passing null into the helper.
