Object source is not supported

Error message

Object source is not supported

What it means

Gbase8sAgent.getObjectSource supports only VIEW; any other (or null) object type throws UnsupportedOperationException with the fixed message 'Object source is not supported'. The type is trimmed and upper-cased before comparison, so only genuinely non-view types fail.

Solutions

1. Only request VIEW object sources from the Gbase8s driver
2. Use procedure/table-specific DDL APIs for other object kinds
3. Pre-check the object type and skip unsupported kinds with a clear user message

Example fix

// before
ObjectSource src = agent.getObjectSource(schema, name, "PROCEDURE");
// after
if ("VIEW".equalsIgnoreCase(objectType)) {
    ObjectSource src = agent.getObjectSource(schema, name, objectType);
} else {
    throw new UnsupportedOperationException("Gbase8s object source only supports VIEW");
}

if (objectType == null || !objectType.trim().equalsIgnoreCase("VIEW")) { throw new UnsupportedOperationException("GBase8s object source only supports VIEW"); }

static boolean supportsGbase8sSource(String t) { return t != null && t.trim().equalsIgnoreCase("VIEW"); }

try { src = agent.getObjectSource(schema, name, type); } catch (UnsupportedOperationException e) { log.info("GBase8s does not expose source for type {}", type); return Optional.empty(); }

When it happens

Trigger: Calling getObjectSource(schema, name, objectType) with null, empty, or a non-VIEW type such as 'TABLE', 'PROCEDURE', or 'FUNCTION'.

Common situations: Generic tooling requests source for procedures or tables; null type from missing metadata; callers expecting parity with other drivers that support more object kinds.
