I'm seeing the following error when running cypress open. I have configured plugins as specified.

Error running plugin

The following error was thrown by a plugin. We've stopped running your tests because a plugin crashed.

Are you allowed to run local servers? Otherwise you need to disable the server in the configuration. This does disable updating snapshots via the GUI.

This appears to happen when the update snapshot server is not allowed to bind on the default port `2121.

I fixed it by changing the default port for the update snapshot server in cypress.json like so:

{
  "env": {
    "cypress-plugin-snapshots": {
      "serverPort": 8081 // Port number for  "update snapshot server"
    }
  }
}

i have ran into the same issue, and tried changing the serverPort but still see EACCES 127.0.0.1:2121. I don't think it's reading from serverPort at all?

solved; i had my cypress.json in the wrong place. this works
