const joi = require('joi');

joi
  .string()
  .custom((v) => v.slice(1))
  .custom(
    async (v) =>
      await new Promise((res) => setTimeout(res, 10000, v.toUpperCase()))
  )
  .custom(
    async (v) => await new Promise((res) => setTimeout(res, 10000, v, 'b'))
  )
  .validateAsync('foobar')
  .then(console.log)
  .catch(console.error);

The thrid custom validator recieves an unresolved promise (current workaround v=await v; ...)
