I can’t get rid of this error no matter what I try… can anyone help me please?
ERROR (node:9) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

Here’s my code:

exports.handler = (event, context, callback) => {
  main(event)
    .then(response => {
      console.log(response);
      callback(null, response);
    })
    .catch(error => {
      console.log(error);
    });
};

async function main(event, callback) {
  try {
    const client = new faunadb.Client({
      secret: process.env.SECRET
    });

    const reservation = JSON.parse(event.body);
    let reservationBlockRef = null;

    if (reservation.reservationBlock) {
      reservationBlockRef =
        reservation.reservationBlock.reservationBlock.ref['@ref'].id;
    }

    // double check here to see if a reservation block exists
    if (!reservationBlockRef) {
      const { data } = await client.query(
        //query
      );

      for (let block of data) {
        if (
          block.data.start_time === reservation.start &&
          block.data.end_time === reservation.end
        ) {
          reservationBlockRef = block.ref.id;
        }
      }
    }

    // if it really doesn't exist at this point, we're creating one
    if (!reservationBlockRef) {
      // first create the block then create the reservation and add it to the block
      const response = await client.query(
        //query
      );
      return new Promise(resolve => {
        resolve({
          headers: {
            'Access-Control-Allow-Origin': '*'
          },
          statusCode: 200,
          body: JSON.stringify(response)
        });
      });
    }

    // if the request was sent with a block, or we found a block previously
    const res = client.query(
          // query
    );
    return new Promise(resolve => {
      resolve({
        headers: {
          'Access-Control-Allow-Origin': '*'
        },
        statusCode: 200,
        body: JSON.stringify(res)
      });
    });
  } catch (error) {
    return new Promise(resolve => {
      resolve({
        headers: {
          'Access-Control-Allow-Origin': '*'
        },
        statusCode: 200,
        body: JSON.stringify(error)
      });
    });
  }
}

Hey @danem,
Do you get that warning in your function logs? If so, could you please share your Netlify URL so we can check them out?
