report Template raises error at "Journal (Source) co-citation analysis"

[rkrug]

bibliometrix     * 4.1.4     2023-10-19 [1] Github (massimoaria/bibliometrix@2e98060)
openalexR        * 1.2.2     2023-10-20 [1] local

I am using openalexR to get my data through a snowball search, convert the nodes for Bibliometrix using

ref.rds.zip

snowball <- readRDS("ref.rds")
M <- snowball$nodes[1:10,] |>
    oa2bibliometrix()

When I now try to do the "Journal (Source) co-citation analysis":

M <- metaTagExtraction(M, "CR_SO", sep = ";")

r$> NetMatrix <- biblioNetwork(M, analysis = "co-citation", network = "sources", sep = ";")
[1] "Field CR_SO is not a column name of input data frame"
Error in crossprod(x, y) : 
  requires numeric/complex matrix/vector arguments

Any ideas what is happening?

The ref.rds is attached.

The issue is related to the Cited Reference field exported by OpenAlex.
OA provides only the reference ids so it's impossible (at the moment), for bibliometrix, to extract source names from references.

Thanks for the explanation. Would it be possible to issue an error message which helps to understand what is going on?
This would make it much easier to understand.
