Hi @edwijk365 ,

Thank you for the contribution. We have a test for validating the PR title. Can you rename the title to something like - chore(datasets): update json dataset filepath type ?

And I see a DCO failure. Please sign off your commits. More info here - https://github.com/kedro-org/kedro/wiki/Guidelines-for-contributing-developers#developer-certificate-of-origin

Thank you
