GRanges error in constructBins

[kalimero0411]

Hello,
I get this error in constructBins. This is after running fastqFilter (dada2) and qAlign (QuasR), as well as renaming the aligned files (.bam, .bam.bai and .bam.txt) to match the samples name. Can you point me to where this error may be coming from?
Thank you.

Error:

Use the provided BAM index file.
Chromosome information is extracted from the BAM file.
Info: reading the aligned read file and processing it into bin-level files...
Error in validObject(.Object) :
