How do I override baseUrl via CLI, nothing seems to work.

[GeorgeXCV]

I have tried the following commands:

"cypress:open:dev": "cypress open --env version=development --config baseUrl=https://google.com",

"cypress:open:dev": "CYPRESS_BASE_URL=https://google.com cypress open --env version=development",

"cypress:open:dev": "cypress open --env version=development,baseUrl=https://google.com",

No matter what, the baseUrl is never changed.

I have a config folder with development.json and production.json using the following format:

{
    "env": {
        "baseUrl": "https://test.web.app/",
    }
}

This is my config file, I have tried commenting out a bunch of code here that could cause conflicts and the baseUrl is still never set via command line so I'm out of ideas.

import { defineConfig } from "cypress";
import * as path from "path";
import * as fs from "fs"

export default defineConfig({
  e2e: {
    async setupNodeEvents(on, config) {
      const version = config.env.version || 'development'
      const configFile = await import(path.join(
        config.projectRoot,
        'cypress/config',
        `${version}.json`
      ));
      const credentialsFile = await import(path.join(
        config.projectRoot,
        'cypress/config',
        'credentials.json'
      ));
      config = {  // Fails even if commented out
        ...config,                    // take config defined in this file
        ...configFile                 // merge/override from the external file
      }
      config.env = {  // Fails even if commented out
        ...config.env,                // 2nd level merge
        ...credentialsFile[version]   // from git-ignored file 
      }
      config.baseUrl = configFile.baseUrl  // Fails even if commented out
     return config
    },
    reporter: 'mochawesome'
  },
});

Figured this out.

"cypress:open:dev": "CYPRESS_BASE_URL=$URL cypress open --env version=development"

The only line I needed to change in my config was the following:

config.baseUrl = config.baseUrl || configFile.env.baseUrl

All my tests were using the following:

 cy.visit(Cypress.env('baseUrl'))

So I needed to change to:

 cy.visit('')

I can now run the script without any argument and it will use the default baseUrl, or I can run URL="https://google.com/ npm run cypress:open:dev and the baseUrl will change
