it also happened about the time that I tried starting to remote debug for the first time on the site. Could it be something with my run configuration?

Hi, what version of the SDK are you using? We've had an issue that could cause this (I'm not sure) but it should be fixed in the latest.

"supertokens-auth-react": "^0.26.0",
    "supertokens-node": "^12.0.0",

I meant the version number of the installed dependency, not just the definition in `package.json`. Anyway, you could try to update them, the fixes I'm thinking of are in 12.0.2&3.

On the other hand - I'm not sure how your run config could mess with how the SDK is working. My best guess is that it starts a separate browser (or a separate browser context) that has a few cookies stuck.

okay I think that updating to the latest versions  resolved it!
