Comment 3 for bug 1982217

Rebased to main: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp1982217-ebook-api-bootstrap-2 / user/jeffdavis/lp1982217-ebook-api-bootstrap-2

This branch also includes a fix for an issue where the holdings format for EbookAPI::Test titles displayed as "undefined" instead of "ebook".

You can test the fix on a server with Concerto data as follows:

1. In config.tt2, set ebook_api.enabled = 'true' and ebook_api.ebook_test.enabled = 'true'.
2. Do a keyword search for "tolkien". The results include several records with ebook test holdings.
