The function "convert2df" doesn't work without loading the package through "library(bibliometrix)"

[bhattmaulik]

This refers to bibliometrix version: 5.4.1.

Minimal reproducible example:

# Fresh R session

bibliometrix::convert2df(
    file = "test.bib",
    dbsource = "generic",
    format = "bibtex"
)

Expected:

Successful import.

Actual:

Warning: data set 'bibtag' not found
Error in [.data.frame(bibtag, , "GENERIC")

After that,

library(bibliometrix)

convert2df(
    file = "test.bib",
    dbsource = "generic",
    format = "bibtex"
)

works correctly.
