`/works/{doi}` have started returning 'Resource not found.' for a lot of valid DOIs

[vals]

Hi,

Did something change with the API or database recently? I'm increasingly getting 'Resource not found.' when querying DOIs that works with the doi.org redirect.

An example:

• https://api.crossref.org/works/10.1038/s41467-021-23949-5 - Gives 'Resource not found'.
• https://doi.org/10.1038/s41467-021-23949-5 - Takes you to the paper correctly

A second example:

• https://api.crossref.org/works/10.1038/s41593-021-00880-y - Gives 'Resource not found.'
• https://doi.org/10.1038/s41593-021-00880-y - Takes you to the paper correctly

Best, /Valentine

There was a bug in one of the services that populates the new version of the API we're rolling out (see here if you're unfamiliar: https://www.crossref.org/blog/behind-the-scenes-improvements-to-the-rest-api/ )

It's since been fixed and the examples you reported are working now.

Thank you.
