This is an unexpected error. Please run

pub --trace publish

and include the logs in an issue on https://github.com/dart-lang/pub/issues/new
pub finished with exit code 1

Start with the failing locations named in the trace: package:http/src/io_client.dart:33 and pub/src/oauth2.dart:208, then reproduce the OAuth upload flow with `pub --trace publish`. Done means authorization completes without the `readEventsEnabled=` null error and the package upload can proceed.
