Describe the bug

I would expect the number to be accepted, validation to succeed and the resulting payload object to contain a bignumber.

Instead, despite clearly giving a number, we get a zod validation error stating that a (bignumber) object was verified instead of a number.

TaskPayloadParsedError: Parsing payload with schema failed: [
  {
    "expected": "number",
    "code": "invalid_type",
    "path": [
      "foo"
    ],
    "message": "Invalid input: expected number, received object"
  }
]

To reproduce

Simply run debugTask.
This is all the code:

import { logger, schemaTask } from "@trigger.dev/sdk";
import { bignumber } from "mathjs";
import { z } from "zod";

export const subTask = schemaTask({
  id: "debug-sub-task",
  schema: z.object({
    foo: z.number().transform((val) => bignumber(val)),
  }),
  run: async (_) => {
    // throws err before.
    logger.info("Sub task started");

    return {
      message: "Sub task completed",
    };
  },
});

export const mainTask = schemaTask({
  id: "debug-task",
  schema: z.object({
    someNumber: z.number().default(1),
  }),
  run: async (payload) => {
    const result = await subTask.triggerAndWait({ foo: payload.someNumber });
    logger.info("Sub task result", { result });

    return {
      message: "Main task completed",
    };
  },
});

export default mainTask;
