"facet not supported" bug on rcrossref

Question

trying to extract author affiliations from dois as discussed here -- now trying to use rcrossref instead of pubmedR

I have this code that always gives me this output:

> test <- cr_works(doi = '10.3390/ijms21165655', facet = TRUE)
Warning message:
400 (client error): /works/10.3390/ijms21165655 - This route does not support facet 

Does this mean affiliation information is not available? Unsure what to do here. Please help and thank you!

Answer 1

found a workaround using cr_cn adapted from the method here

ref <- cr_cn(dois = '10.1590/S0104-12902020200348', format = "citeproc-json")

and then author affiliations are accessible using

affil <- ref[["author"]][["affiliation"]]
