Error when using Photon to create new item with 2 relation connections

To give a bit of background, this is my data model (or at least part of it):

model User {
  // Meta
  id        String   @default(cuid()) @id @unique
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  // Data
  auth0Id        String          @unique
  email          String          @unique
  firstName      String
  lastName       String
  picture        String
  private        Boolean         @default(false)
  userChallenges UserChallenge[] @relation(onDelete: CASCADE)
  following      Following[]     @relation(name: "UserFollowing", onDelete: CASCADE)
  followedBy     Following[]     @relation(name: "UserFollowed", onDelete: CASCADE)
  comments       Comment[]       @relation(onDelete: CASCADE)
  likes          Like[]          @relation(onDelete: CASCADE)
  tags           Tag[]           @relation(onDelete: CASCADE)
  challenging    Challenging[]   @relation(name: "UserChallenging", onDelete: CASCADE)
  challengedBy   Challenging[]   @relation(name: "UserChallenged", onDelete: CASCADE)
  reports        Flag[]          @relation(onDelete: NONE)
}

model Update {
  // Meta
  id        String   @default(cuid()) @id @unique
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  //  Data
  text          String
  type          UpdateType
  secret        String        @unique
  userChallenge UserChallenge @relation(onDelete: NONE)
  comments      Comment[]     @relation(onDelete: CASCADE)
  likes         Like[]        @relation(onDelete: CASCADE)
  tags          Tag[]         @relation(onDelete: CASCADE)
}

model Like {
  // Meta
  id        String   @default(cuid()) @id @unique
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  // Data
  user   User   @relation(onDelete: NONE)
  update Update @relation(onDelete: NONE)
}

The resolver I have trouble with is the one where I am trying to create a like:

export const likeMutations = extendType({
  type: 'Mutation',
  definition(t) {
    t.field('createLike', {
      type: 'Like',
      args: { updateId: idArg({ required: true }) },
      async resolve(parent, args, context) {
        return context.photon.likes.create({
          data: {
            update: { connect: { id: args.updateId } },
            user: { connect: { id: context.userId } },
          },
        });
      },
    });
  },
});

Whenever I try to call that resolver with the right arguments, I get the following error:

I tried the same thing with creating a comment and I got the same error.

Fixed with: https://github.com/prisma/prisma/commit/b0df6842459f018a2178867ec728399cfcf47b25

The fix is available in a few minutes on alpha.

Just FYI: The bug had nothing to do with relations. The problem were the fields createdAt and updatedAt in this case. The arguments for the scalar fields in createLike were empty. We had a line that was not setting the default values for those fields in this case. Then the insert failed because the columns have to be not null.

I had to do the migration again as well, it works now, though I found another bug. But this can be closed!
