Checking whether dataset is a list

[Zepeng-Mu]

Hi,

While running coloc susie, accidentally my dataset 2 is NULL, but I get this message:

Error in check_dataset(d, suffix, req = c("beta", "varbeta", "LD", "snp")) : 
  dataset 1: is not a list

I this there is bug that always prints dataset 1 instead of the right one.
Of course I should pre-filter my input datasets, but just want to report this.
