simple functions not working today. CR API change related?

[rossmounce]

I haven't played with rcrossref for a while but it just doesn't seem to be working for me. Perhaps related to #216 ? Or the major upgrade to R 4.1.0?

> cr_members(query = 'ecology', limit = 5)
Error in cr_GET(endpoint = path, args, FALSE, parse = TRUE, ...) : 
  res$response_headers$`content-type` == "application/json;charset=UTF-8" is not TRUE

[sckott]

may have been a temporary issue. is it still happening now? i can't replicate it

[njahn82]

it is related to #216 and changes have become effective today for people not using the Polite or Metadata Plus pool. @rossmounce add your email address and then your request should be handled by the polite pool.

https://github.com/ropensci/rcrossref#register-for-the-polite-pool

[rossmounce]

@njahn82 thank you! I will register for the polite pool.

...and yes that fixed the problem for me. Thanks!

[bmkramer]

The polite pool will transition to the new API version on August 3 (https://www.crossref.org/blog/behind-the-scenes-improvements-to-the-rest-api/) so the issue might re-occur then...

It appears that currently in the API response, headers$content-type is application/json;charset=UTF-8 when using the polite pool, but changed to application/json when using the public pool

This is checked for in R/zzz.R in line 45 stopifnot(res$response_headers$content-type == "application/json;charset=UTF-8")

[njahn82]

{rcrossref} was updated to reflect Crossref's REST API updates for the public and polite pool #216 . Please install the dev version:

remotes::install_github("ropensci/rcrossref")

[MrBungle-Codes]

Hello, I am still having this issue although I registered to the polite pool (email at the .Renviron) and also installed the dev version as indicated. Any help/advice is appreciated. Thanks

Hi @MrBungle-Codes

please re-install rcrossref using the dev version.

remotes::install_github("ropensci/rcrossref")

[MrBungle-Codes]

thank you very much @njahn82 !!... that solves the issue for me.

[Adafede]

Do we still have to install the dev version from GitHub as a workaround?

[njahn82]

Yes, please install dev version. Still not updated the version on CRAN

[Tom-K-UKRI]

To note this issue is still occurring and it was solved by installing the dev version (I already had email in Renviron). So presumably still not updated on CRAN

[njahn82]

The updated version is now available on CRAN, thanks for you patience!
