cannot coerce type 'closure' to vector of type 'any'

Dear Friends,

I am getting an error in the biblioshiny "cannot coerce type 'closure' to vector of type 'any' "

I merged my 4 Gb data and compressed it into 1.24 Gb data in a zipped folder.

While putting my data from the zipped folder into Biblioshiny, I am getting the above error.

Please, anyone in this R Community, kindly help with this by step by step.

I am new in this biblioshiny, Please.
