Conflict between Admin and Anonymous plugins – 500 error

Hello, I'm having an issue with two plugins: Admin and Anonymous. When I try to use Anonymous while the Admin plugin is enabled, I get a 500 error. However, if I disable the Admin plugin, Anonymous works perfectly. Is there a specific configuration I need to set up? Or are these two plugins simply not compatible with each other? I haven’t found anything about this in the documentation or the issues section. If anyone has any idea, I’d really appreciate the help! Thanks in advance 😊

I couldn't reproduce it on my end. Could you send me your auth config?

Yes, of course, in auth.ts: 
export const auth = betterAuth({
    database: prismaAdapter(prisma, {
        provider: 'postgresql'
    }),
    user: {
        additionalFields: {
            role: {
                type: 'string'
            },
            plan: {
                type: 'string'
            }
        }
    },
    socialProviders: {
        // --- Google
    },
    plugins: [
        magicLink({
            sendMagicLink: async ({ email, url }) => {
                // --- Send email
            }
        }),
        stripe({
            stripeClient,
            stripeWebhookSecret: env.STRIPE_WEBHOOK_SECRET,
            createCustomerOnSignUp: true,
            subscription: {}
        }),
        /*anonymous({
            emailDomainName: env.RESEND_DOMAIN
        }),*/
        customSession(async ({ user, session }) => {
            // --- Fetch User ---
            const userNew = await prisma.user.findUnique({
                where: {
                    id: user.id
                }
            })

            // --- Return ---
            return {
                session,
                user: {
                    ...user,
                    ...userNew
                }
            }
        }),
        admin()
    ]
})
export const auth = betterAuth({
    database: prismaAdapter(prisma, {
        provider: 'postgresql'
    }),
    user: {
        additionalFields: {
            role: {
                type: 'string'
            },
            plan: {
                type: 'string'
            }
        }
    },
    socialProviders: {
        // --- Google
    },
    plugins: [
        magicLink({
            sendMagicLink: async ({ email, url }) => {
                // --- Send email
            }
        }),
        stripe({
            stripeClient,
            stripeWebhookSecret: env.STRIPE_WEBHOOK_SECRET,
            createCustomerOnSignUp: true,
            subscription: {}
        }),
        /*anonymous({
            emailDomainName: env.RESEND_DOMAIN
        }),*/
        customSession(async ({ user, session }) => {
            // --- Fetch User ---
            const userNew = await prisma.user.findUnique({
                where: {
                    id: user.id
                }
            })

            // --- Return ---
            return {
                session,
                user: {
                    ...user,
                    ...userNew
                }
            }
        }),
        admin()
    ]
})
and in authClient: 
import {
    magicLinkClient,
    customSessionClient,
    //anonymousClient,
    adminClient
} from 'better-auth/client/plugins'

// --- Auth Client ---
export const authClient = createAuthClient({
    plugins: [
        magicLinkClient(),
        //anonymousClient(),
        customSessionClient<typeof auth>(),
        stripeClient({
            subscription: true
        }),
        adminClient()
    ]
})
import {
    magicLinkClient,
    customSessionClient,
    //anonymousClient,
    adminClient
} from 'better-auth/client/plugins'

// --- Auth Client ---
export const authClient = createAuthClient({
    plugins: [
        magicLinkClient(),
        //anonymousClient(),
        customSessionClient<typeof auth>(),
        stripeClient({
            subscription: true
        }),
        adminClient()
    ]
})
For the moment they are commented And I call it in the layout: 
/*
'use client'

// --- Dependencies ---
import { useEffect } from 'react'
import { signIn, authClient } from '@/lib/auth-client'*/

// --- Components: Layout ---
import Header from '@/components/layout/header'
import Footer from '@/components/layout/footer'

// --- Layout:Space ---
export default function HomeLayout({
    children
}: Readonly<{ children: React.ReactNode }>) {
    /*useEffect(() => {
        ;(async () => {
            const { data, error } = await signIn.anonymous()
            console.log('DATA', data)
            console.log('ERROR', error)
        })()
    }, [])*/

    // --- Render ---
    return (
        <div className="relative w-full overflow-x-hidden">
            <Header />
            <div className="pt-14">{children}</div>
            <Footer />
        </div>
    )
}
/*
'use client'

// --- Dependencies ---
import { useEffect } from 'react'
import { signIn, authClient } from '@/lib/auth-client'*/

// --- Components: Layout ---
import Header from '@/components/layout/header'
import Footer from '@/components/layout/footer'

// --- Layout:Space ---
export default function HomeLayout({
    children
}: Readonly<{ children: React.ReactNode }>) {
    /*useEffect(() => {
        ;(async () => {
            const { data, error } = await signIn.anonymous()
            console.log('DATA', data)
            console.log('ERROR', error)
        })()
    }, [])*/

    // --- Render ---
    return (
        <div className="relative w-full overflow-x-hidden">
            <Header />
            <div className="pt-14">{children}</div>
            <Footer />
        </div>
    )
}
