I’m trying to retrieval metadata from this item (Crossref Metadata Search) with the REST API and get the error: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data (https://0-api-crossref-org.libus.csd.mu.edu/v1/works/10.15252/embj.2020105043)
The same happen with https://0-api-crossref-org.libus.csd.mu.edu/v1/works/10.15252/embj.2020105043
I don’t see where the problem can be. Any ideas to solve it?
Thanks in advanced,

Hi @lbermudez ,
Thanks for your message.
We recently migrated the backend of the Public pool of the REST API to Elasticsearch (from Solr), as you can read more about here: Behind the scenes improvements to the REST API - Crossref.
Looks like we may have a bug with how those new DOIs are being ingested into the Public pool of the REST API. They’re present in the Polite pool (when identifying myself with a mailto parameter):

https://0-api-crossref-org.libus.csd.mu.edu/works/10.15252/embj.2020105043?mailto=support@crossref.org
I’ve opened an issue with our technical team to investigate: DOIs missing in the Public pool of the REST API - please push! (#1387) · Issues · crossref / Issue Tracker · GitLab
Please let me know if you have any additional questions.
Kind regards,
Isaac
Hi @lbermudez ,
These DOIs are now appearing in the Public pool of the API, as you can see here:
