In the pharmacovigilance section: https://platform-docs.opentargets.org/drug/pharmacovigilance#computational-pipelines-and-datasets

The link that points to blacklisted events should use this path: https://github.com/opentargets/platform-etl-openfda-faers/blob/master/src/main/resources/blacklisted_events.txt
