Internet identity integrate issue

[ccyanxyz]

I deployed the internet identity canister in a local replica, try to integrate it with my application, but I often get this error:

Anyone know how to fix this?

Are you deploying it with:

II_ENV=development dfx deploy --no-wallet --argument '(null)'

@Hazel

II_ENV=development dfx deploy --no-wallet --argument ‘(null)’

Problem fixed, thanks!
