Parameter matching in routes fails with underscores

Environment

Name	Version
msw	0.21.2
node	10.16.3
OS	Windows 10

Request handlers

// Example of declaration. Provide your code here.
import { setupServer } from 'msw/node'
import { rest } from 'msw'

const server = setupServer(
  rest.get('/project/project_id', () => {
      // handle request
  })
)

server.listen()

Actual request

fetch('/project/4').then((res) => res.json())

Current behavior

Request fails to match.

Expected behavior

Request should be matched by msw.

Note switching the URL parameter name to be projectId results in the matching working as expected. I could not see any restrictions on variable naming in the documentation hence raising the issue as it took quite a while to figure out why the request was not being matched and don’t want others to fall into the same trap.

Thanks to @timdeschryver the issue has been fixed and published in node-match-path@0.5.1. If you re-install your dependencies the fix should propagate in.
