Description

Our usage of Auth0 is pretty simple. After the user has been logged in we just attach the access token to network calls and verify them server side.

const useApi = (): Api => {
  const { getAccessTokenSilently } = useAuth0()
  const backend = axios.create({ baseURL: apiUri, timeout: 10000 })
  backend.interceptors.request.use(
    async config => {
      const accessToken = await getAccessTokenSilently()
      config.headers["Authorization"] = `Bearer ${accessToken}`
      return config
    },

    async error => {}
  )
}  

We have gotten user reports that they get error in title. Our understanding is that this error is unrecoverable so we log the user out and force them to re-authenticate. We have a couple of thousand weekly users and this happens to maybe 2% of them.

One log id as an example: 90020251109193144192993000000000000001223372093304300940

Our top level provider:

 <Auth0Provider
        key={`${domain}-${clientId}-${audience}`} // This forces remount when values change
        domain={domain}
        clientId={clientId}
        authorizationParams={{
          redirect_uri: getFrontEndHost(),
          audience: audience,
        }}
        cacheLocation={"localstorage"}
        onRedirectCallback={onAuth0Redirect}
        useRefreshTokens={true}
      >
        <AppWithTheme />
</Auth0Provider>

Reproduction

Seems to happen randomly, a few times a week for affected users. Mostly on iOS and MacOS devices but we've also seen it happen on Windows machines.

Additional context

A similar issue happens when we use the react native version, but only for iOS devices. We allow overlap for expiring refresh tokens (120 seconds). Our refresh token are set to last one year, and we're currently seeing this multiple times a week for users.
