### Describe the Bug

### **When generating migration -**

If I add default value for BigInt column it causes this error:
TypeError: Do not know how to serialize a bigint

So if we add column like this:

```ts
column: bigint("column", {
mode: "bigint",
})
.notNull()
.default(0n);
```

that will then produce that error

But if we do it like this:

```ts
column: bigint("column", {
mode: "bigint",
})
.notNull()
.default(0 as unknown as bigint);
```

then it will work.

So it's not able to create proper json file from schema which prevents it to create SQL file.
