NextJS Auth0 getAccessToken with refresh token only work for the first time

Help

I have NextJs app and and NestJs Web API.
The NextJs will get an access token and forward it to the API, here is the code:

const { accessToken } = await getAccessToken(req, res, { refresh: true });

Here are my settings:

  • Refresh Token Rotation: Enable
  • Reuse Interval: 60 seconds.

My refresh token seems not to be updated and after 60 seconds passed, the error message appeared: AccessTokenError: The request to refresh the access token failed. CAUSE: invalid_grant (Unknown or invalid refresh token.)

  1. Seem the token was updated but the new refresh token was not updated. Is my code above correct or am I missing something?
  2. Concern: why does the token always get refreshed every time the getAccessToken method gets called even it has not yet expired?

Thanks,

I followed this.
