Description of the bug/issue

If we send a request on /execute/sync endpoint and it returns the below response:

Response 404 POST /session/820fa3e285be4a9b4419478cb341447c/execute/sync (10ms)
   {
     value: {
       error: 'stale element reference',
       message: 'stale element reference: stale element not found\n' +
         '  (Session info: chrome=120.0.6099.129)',
       stacktrace: ''
     }
  }

Then Nightwatch exits with the below error (while the browser stays open):

Error
   unhandledRejection: stale element reference: stale element not found
  (Session info: chrome=120.0.6099.129)
StaleElementReferenceError: stale element reference: stale element not found
  (Session info: chrome=120.0.6099.129)
    at Object.throwDecodedError (/Users/priyansh/Projects/test_projects/create-nightwatch-demo/yyyy/node_modules/selenium-webdriver/lib/error.js:524:15)
    at parseHttpResponse (/Users/priyansh/Projects/test_projects/create-nightwatch-demo/yyyy/node_modules/selenium-webdriver/lib/http.js:601:13)
    at Executor.execute (/Users/priyansh/Projects/test_projects/create-nightwatch-demo/yyyy/node_modules/selenium-webdriver/lib/http.js:529:28)

    at async Driver.execute (/Users/priyansh/Projects/test_projects/create-nightwatch-demo/yyyy/node_modules/selenium-webdriver/lib/webdriver.js:745:17)

It should be noted that the error is handled properly if it happens on some /elements endpoint, like below:

# Request/Response
Request POST /session/a3c2b6a1f32d8e288b366f25eec95c54/element/3ACAFAB1F78948D78EE676688D83C048_element_8/elements  
   { using: 'css selector', value: 'option[value =Mission]' }
Response 404 POST /session/a3c2b6a1f32d8e288b366f25eec95c54/element/3ACAFAB1F78948D78EE676688D83C048_element_8/elements (12ms)
   {
     value: {
       error: 'stale element reference',
       message: 'stale element reference: stale element not found\n' +
         '  (Session info: chrome=120.0.6099.129)',
       stacktrace: ''
     }
  }

gives following handled error/failure: image
