GoogleAnalytics.Error.UnableToReadFromRep

Error message

GoogleAnalytics.Error.UnableToReadFromRep

What it means

GaInputStepMeta.readRep wraps any exception raised while loading Google Analytics step settings from a Kettle repository into a KettleException with the localized 'GoogleAnalytics.Error.UnableToReadFromRep' message. It guards the repository reads for ga fields, conversion masks and output types, defaulting invalid output types to TYPE_STRING before the catch.

Solutions

  1. Check the nested cause for the real repository/driver failure and fix connectivity or schema issues.
  2. Reconnect the repository and reload the transformation.
  3. Re-save the step from a working client to restore missing attributes.
  4. Verify plugin version compatibility with the repository content.

Example fix

// before
TransMeta tm = new TransMeta( rep, id, metaStore ); // throws on stale connection

// after
if ( !rep.isConnected() ) {
  rep.connect( user, pass );
}
TransMeta tm = new TransMeta( rep, id, metaStore );
Defensive patterns

Strategy: try-catch

Validate before calling

if ( rep == null || !rep.isConnected() ) {
  rep.connect( user, pass );
}

Try / catch

try {
  transMeta = new TransMeta( rep, id, metaStore );
} catch ( KettleException e ) {
  log.error( "readRep failed: " + e.getMessage(), e.getCause() );
}

Prevention

When it happens

Trigger: Calling readRep(Repository, IMetaStore, ObjectId, List<DatabaseMeta>) when rep.getStepAttributeString/... calls for id_step throw — dead repository connection, missing step row, or repository driver error.

Common situations: Opening a stored transformation while the repository DB is unreachable; step attributes partially deleted; repository schema changed between Pentaho versions so expected attributes are absent.

Understand the failure class

Background: "failed to read file", EACCES, ENOENT and "could not read <path>" errors: when a program can't read a file from disk — this error's family across 49 libraries.
