How to figure out stripe issue for payout / transfer with Strapi

Question

I am going to implement transfer and payout functional with stripe between accounts using node js. But I met one issue to implement this one.

Code:

const stripe = require('stripe')('****');

try {
        cardInfo = await PayInfo.findOne({user_id: uid});
        if (!cardInfo ) {
          return ctx.badRequest(
            null,
            formatError({
              id: 'PayInfo.create.findByUserId.error',
              message: 'User is not available',
            })
          );
        }

        let targetId = cardInfo.account_id;
        let payoutState = null;

        try {
          const payoutState = await stripe.transfers.create({
            amount: 400,
            currency: 'usd',
            destination: targetId,
            source_type: 'bank_account',
          });

          await record.create({
            order_id: id,
            user_id: user.id,
            payment_id: payoutState.id,
            transaction: 'transfer',
            amount: 400,
            state: payoutState.reversed ? 'failed' : 'succeeded',
          });
        } catch (error) {
          return ctx.send(null, {
            error,
            payoutState,
          });
        }
      } catch (e) {
        return ctx.badRequest(
          null,
          {
            error: e,
          }
        );
      }

But I met this issue message from it. If I delete stripe integration part then it works well. - so wired.

{
actual: false
code: "ERR_ASSERTION"
expected: true
generatedMessage: false
operator: "=="
}

I am not sure what I was wrong, would you let me know on it please? Thanks.
