Expo plugin isn't a valid plugin
Just set up an external backend for my app and for some reason the expo plugin from
import { expo } from "@better-auth/expo"; isnt compatible with the type BetterAuthPlugin.

with this config:
export const auth = betterAuth({
trustedOrigins: ["myapp://"],
plugins: [expo()],
database: prismaAdapter(prisma, {
provider: "postgresql",
}),
emailAndPassword: {
enabled: true,
},
socialProviders: {
google: {

clientSecret: process.env.GOOGLE_CLIENT_SECRET!,

Make sure both the expo and better-auth are up-to-date. @Dominik
They are both on 1.2.7, I think thats the newest version
Yea just checked the github seems like it
I also just reinstalled my packages still doesnt seem to be working
how about refreshing ts-server?
Done that too same thing somehow
Anyone got any idea?
Have you tried a fresh project and maybe a different package manager? Worth a shot
Also could you give us your package.json file, or any other information about your setup?
its basically a brand new project only has the expo plugin in it
As for the package file its basically just this

maybe try a different package manager
