Better Auth 1.2.9 + Prisma: P2000 error when login

Hi everyone,
I'm using Better Auth v1.2.9 with Prisma as the adapter, and I'm encountering a PrismaClientKnownRequestError (P2000) when trying to log in using the Discord provider.

Here's the relevant error log:

SERVER_ERROR: PrismaClientKnownRequestError:

Invalid prisma.verification.create() invocation:


The provided value for the column is too long for the column's type. Column: value

meta: { modelName: 'Verification', column_name: 'value' }
}


From what I understand, Better Auth is trying to create a record in the Verification table, but the value being inserted into the value column is too long for the column's data type.


My Schema


model User {
id String @id
name String
email String
emailVerified Boolean
image String?
createdAt DateTime
updatedAt DateTime
sessions Session[]
accounts Account[]

@@unique([email])
@@map("user")
}

model Session {
id String @id
expiresAt DateTime
token String
createdAt DateTime
updatedAt DateTime
ipAddress String?
userAgent String?
userId String
user User @relation(fields: [userId], references: [id], onDelete: Cascade)

@@unique([token])
@@map("session")
}

model Account {
id String @id
accountId String
providerId String
userId String
user User @relation(fields: [userId], references: [id], onDelete: Cascade)
accessToken String?
refreshToken String?
idToken String?
accessTokenExpiresAt DateTime?

@@map("account")
}

model Verification {

@@map("verification")
