You received this error because the reads in your BAM files do not contain read groups. The main reason why this would occur is that you uploaded a BAM file for your sample that was produced in a way so that it does not have read groups.
Solution 1 - Convert your BAM file to FASTQ
We have a pipeline called "BAM to FASTQ" that will create a new sample with FASTQ file(s) after converting your BAM file to FASTQ. Once you have run that pipeline, you will then need to run the alignment pipeline (e.g. "DNA-Seq QC, Alignment (BWA)").
