Fatal error in chip seeker

Dear all,
I’m trying to annotate chip peaks obtained with MACS2 using chip seeker. But it showing fatal error as Import genomic features from the file as a GRanges object … OK
Prepare the ‘metadata’ data frame … OK
Make the TxDb object … OK
Error: subscript contains invalid names.

I saw some post similar to this but no one has responded yet. Any one has encountered similar problem and solved it. Your answer will be highly appreciated.

Yeh… I am also facing the same issue. I still do not know how to encounter this one.
