Unsupported action type: ${actionType}

Error message

Unsupported action type: ${actionType}

What it means

EasysearchCatalog.previewAction only knows how to describe CREATE_TABLE, DROP_TABLE, CREATE_DATABASE and DROP_DATABASE actions; any other ActionType reaches the else branch and throws UnsupportedOperationException.

Solutions

1. Only request previews for supported actions (create/drop table or database).
2. Skip or special-case preview for unsupported action types in your tooling.
3. Update previewAction to handle the missing ActionType (e.g. TRUNCATE_TABLE) if you maintain the connector.

Example fix

// before
} else if (actionType == ActionType.DROP_DATABASE) {
    return new InfoPreviewResult("delete index " + tablePath.getTableName());
} else {
    throw new UnsupportedOperationException("Unsupported action type: " + actionType);
}
// after
} else if (actionType == ActionType.TRUNCATE_TABLE) {
    return new InfoPreviewResult("delete and create index " + tablePath.getTableName());
} else {
    throw new UnsupportedOperationException("Unsupported action type: " + actionType);
}

Set<ActionType> supported = EnumSet.of(ActionType.CREATE_TABLE, ActionType.DROP_TABLE,
    ActionType.CREATE_DATABASE, ActionType.DROP_DATABASE);
if (!supported.contains(actionType)) {
    throw new IllegalArgumentException("Preview not supported for " + actionType);
}

try {
    result = catalog.previewAction(actionType, tablePath, ignoreIfNotExists);
} catch (UnsupportedOperationException e) {
    // skip preview or fall back to generic description
}

When it happens

Trigger: Calling previewAction with an ActionType other than the four handled ones, e.g. TRUNCATE_TABLE or any newly added ActionType enum value not yet wired into the preview logic.

Common situations: Job configs using truncate/other auto-create actions whose preview is requested; upgrading SeaTunnel adds a new ActionType while the connector's preview switch lags behind.
