BUG: oa_query() is not working when multiple_id is set

[rkrug]

Hi

I am running

openalexR 2.0.0 2025-04-05 [1] CRAN (R 4.5.0)

Running

oa_query(
    identifier = c("W2162348455", "W2746723710"),
    multiple_id = TRUE
)

Results in

Identifier is missing, please specify filter or search argument.
NULL

Following on this, is there a reason why I have to specify multiple_id and not that it is set to isTRUE(length(identifier)>1))?

Thanks

Rainer
