Help on Error in .processStrand("+", bam)

[KoHaku55]

Hi
I have run the readBAM function for the same file 2 years ago on a Linux PC.
This month, I installed a new NucleR on my Windows laptop. I run the same command and files.
I got this error

Error in .processStrand("+", bam) :
ERROR: Mate selection for + strand is invalid

I try to figure out but I still don't have the solution yet. Could you please help ?

Thank you in advance !
Park.
