oa_fetch authors returns "Error in rbind(deparse.level, ...) : numbers of columns of arguments do not match" #197

Dear OpenAlexR team,

When I try to retrieve author data using multiple OA IDs, I sometimes run into the following error:

Error in rbind(deparse.level, ...) : numbers of columns of arguments do not match

Here is an example with a list of IDs that returns an error for me:

id_list <- c("https://openalex.org/A5060327933", "https://openalex.org/A5043212291", "https://openalex.org/A5013893618",

"https://openalex.org/A5047141474")

output <- oa_fetch(
    entity = "authors", 
    openalex_id = id_list)

It seems to happen when calls for different IDs return different numbers of columns with author info, but I could not figure out when does it exactly happen (as sometimes I manage to retrieve a few hundred IDs just fine). I can solve this by retrieving info for the results one by one and tidying it up manually, but I am still wondering why some calls are failing like this.

Thanks in advance!

Thanks! I can reproduce the error. I've proposed a PR for the fix - you can see if it also works for you with:

remotes::install_github("ropensci/openalexR#198")

Thanks so much! It now also works on my side; and I don't see any errors when pulling some other IDs that were problematic in the past.
