Hi @trevor! Can you provide more details about your setup, such as which version of Sentry you are using and what type of installation is it (docker-compose based from our onpremise repo, pip based custom, or something else?)
Also our docs mention some admin permissions both on Sentry and Bitbucket side: https://docs.sentry.io/workflow/integrations/global-integrations/#bitbucket - maybe you should try granting those too first?
