How To Troubleshoot Build Failures (Linux OS)

Krutika can you add one more example:

BE#640720 Build failed: base table <table name> was not completed as expected.
Failed to read row: 0, Connector (SQL compilation error:
invalid number of result columns for set operator input branches, expected 46, got 45 in branch 2).

Most likely issue in the custom import query or on the target table. Please check if there are right amount of columns used in the query and refresh table schema.
