Hi @gustavotonini!

I've tried to simulate this issue and I had no success, can you simulate it on the test drive installation?
https://ojs33.testdrive.publicknowledgeproject.org (login: admin/testdrive).

Once you start typing on the field, a single request will be made to /index.php/journal/api/v1/vocabs?vocab=submissionKeyword, I guess there might be something wrong on the output on your local installation, if you spot something unexpected, let us know.

I'll close this issue for now.
