Description
We have read a file and created a PCollection of Strings where each record represent one line on the file. There after we have multiple PTransforms to validate the records. In the end The Pcollection was filtered into two PCollection , one with all valid records and one with all invalid records. Now both the pcollections are stored to respective mongo db collections . In case if any of these pcollection is empty we are facing below exception trace :
