I have already connector of Office365Users in Power Apps Connections

Start by reproducing pac code add-data-source -a "apiId" -c "connectionId" with the reported Office365Users connection and inspect the CLI request path associated with the command. Done means identifying the failed request or missing context and providing a fix or a more useful error that explains the failure.
