Describe the bug
I get a "ECONNREFUSED ::1:3000" error when I try to specify a local server in my netlify.toml file (i.e. yarn start):

  [plugins.inputs.preBuild]
  enable = true
  spec = "src/components/**/*.spec.cy.js"
  start = 'yarn start'
  wait-on = 'http://localhost:3000'
  wait-on-timeout = '30' # seconds

(the entire toml file is below if you need it)

Oddly I can see from the logs that the local server is running - the problem is connecting to it.

I also have a postBuild section but no "start" option because the default suffices (adding start, wait-on, and wait-on-timeout to postBuild while removing preBuild gives me the same connection error).

Entire netlify.toml:

[build]
command = "yarn install && yarn build"
publish = "build"
[build.environment]
# cache Cypress binary in local "node_modules" folder
# so Netlify caches it
CYPRESS_CACHE_FOLDER = "./node_modules/CypressBinary"
[[plugins]]
  package = "netlify-plugin-cypress"
  [plugins.inputs]
  configFile = "./cypress.config.js"
  [plugins.inputs.preBuild]
  enable = true
  spec = "src/components/**/*.spec.cy.js"
  start = 'yarn start'
  wait-on = 'http://localhost:3000'
  wait-on-timeout = '30' # seconds
  [plugins.inputs.postBuild]
  enable = true

(changing the timeout to 90 seconds didn't fix the problem)
