Prisma

really failing at this one: from the backend, trying to query a node where a relation matches:

```
const conversationExists = await ctx.db.exists.Conversation({
  participants_every: { AND: [{ id: userId }, { id: currentUserId }] }
});
```

```
type Conversation {
  id: ID! @unique
  participants: [User!]!
}
```

I don't understand your query. It is semantically identical to these two:

```
const conversationExists = await ctx.db.exists.Conversation({
  participants_every: { id: userId }
});
``` 


```
const conversationExists = await ctx.db.exists.Conversation({
  participants_every: { id: currentUserId }
});
```

Oh, I think I get it. You are misunderstanding the `_every` filter. `_every` means "get me all conversations that fulfill _all_ of the following requirements". You probably want to ask for `_some` instead.
