Array to string conversion in UnionHandler

[G4Zz0L1]

When calling getAllLibraries(), the SDK fails with "Array to string conversion" in UnionHandler.php line 172.

Root cause:

$unionName = implode('|', $type['params']);

However, $type['params'] contains arrays, not strings. When implode() tries to join them, PHP throws the warning.
