promise - How to handle errors using Knex.js

I am using nest.js with knex and try to make error handler for my application. So I can update my data in database using this code:

const updatedProject = await this.knex('projects')
  .update('name', body.name) // body.name id new name which come from frontend
  .where('id', id) // id also come from frotend and I compare this id and id in database
  .returning('*');
return updatedProject[0];

But if I try to update the project whith id which don't exist I have not any errors. I try catch them by this way but this is didn't work

const updatedProject = await this.knex('projects')
  .update('name', body.name)
  .where('id', id)
  .returning('*')
  .catch((error) => console.error(error));
return updatedProject[0];

How can I create and catch error if reqest is wrong?
