CubeInputMeta.Exception.UnableToLoadStepInfo

Error message

CubeInputMeta.Exception.UnableToLoadStepInfo

What it means

CubeInputMeta.readData parses the step's XML definition (file name, row limit, add-to-result flag). If any XMLHandler access throws, it wraps the cause in this KettleXMLException indicating the step info could not be loaded from XML.

Solutions

1. Fix or regenerate the transformation XML so the CubeInput step node contains <file><name> and <limit> tags.
2. Re-save the transformation from Spoon to produce well-formed XML.
3. Check the root cause (the wrapped exception) for the exact XML parsing problem.

Example fix

// before
<step><type>CubeInput</type></step>
// after
<step><type>CubeInput</type><file><name>data.cube</name></file><limit>0</limit></step>

try {
  meta.loadXML( stepnode, databases, metaStore );
} catch ( KettleXMLException e ) {
  logError( "CubeInput step XML invalid, re-save transformation in Spoon: " + e.getMessage(), e );
}

When it happens

Trigger: loadXML encounters a malformed stepnode subtree — missing/malformed <file><name> or <limit> tags, or corrupted transformation XML.

Common situations: Hand-edited .ktr files; transformations exported from newer PDI versions parsed by older ones; truncated XML files.
