See the docs of OError.tag: https://github.com/overleaf/o-error#long-stack-traces-with-oerrortag (currently at 221dd902e7bfa0ee92de1ea5a3cbf3152c3ceeb4) I am tagging all errors at each async hop. Most of the controller code will only ever see already tagged errors -- or new errors created in our app code. They should have enough info that we do not need to tag them again.
