hi i have a question. The front end is developed with next.js and the back end with nest.js. When i login with your Google account, When i send a request to http://localhost:3001/api/auth/signinup,

data: { error: 'invalid_grant', error_description: 'Bad Request' }

is returned from GoogleAPi. But the login itself succeeds. What is the cause here?

hey @kazumo Are you using a custom UI or our pre built UI? Can i see the network tab in inspect element screenshot?

i using custom UI sure, this is screenshot

right, so you are calling the signinup function from a usEffect right? In dev mode, react fires useEffect two times. So that's why this is happening. It won't happen in prod, so you can ignore it
