@himilp108 just posting an error message is unlikely to get you any good assistance. Could you provide some context?

Hi, 

I received this error when trying to execute the following code

CALL gds.beta.pipeline.linkPrediction.train('lpgraph', {
pipeline: 'lp-pipeline',
modelName: 'lp-pipeline-model',
metrics: ['AUCPR'],
randomSeed: 42
}) YIELD modelInfo, modelSelectionStats
RETURN
modelInfo.bestParameters AS winningModel,
modelInfo.metrics.AUCPR.train.avg AS avgTrainScore,
modelInfo.metrics.AUCPR.outerTrain AS outerTrainScore,
modelInfo.metrics.AUCPR.test AS testScore,
[candidate IN modelSelectionStats.modelCandidates | candidate.metrics.AUCPR.validation.avg] AS validationScores
 
I am not sure what is wrong as metrics is a required configuration property.
