@ivan-tymoshenko could you please try to restart the CI? Seems the fail is not related to the changes in this PR

[gurgunday]

Seems like there is an issue on node 14?

This is the 4th run

[mcollina]

Yes. macos-latest gha env is now arm based. There is no Node v14 for arm. It's failing everywhere.

Either we test on older Mac envs or we just ignore that combo.

[Uzlopak]

Lets ignore it.

[gurgunday]

Just to make sure, can you please add another test for double quote as well:

const stringify = build({
    type: 'object',
    properties: {
      '"': { type: 'string' }
    },
    required: [
      '"'
    ]
  })

[gurgunday]

yeah lgtm, that regex seems necessary
