webdriverio browser.executeAsync throws Error setting arguments in IE11

Question

I am getting Error setting arguments for script error while trying to run browser.exectueAsync in IE 11 .

the code I'm executing is

const result = browser.executeAsync(
   (url, body, done) => {
     fetch(url, {
       method: 'POST',
       credentials: 'same-origin',
       headers: {
         'Content-Type': 'application/json',
       },
       body: JSON.stringify(body),
     })
    .then(resp => resp.json())
    .then(data => done(data));
   },consentsUrl,consentRequestBody);
browser.waitUntil(() => result.value.updated === true);

This works fine on Chrome. so not sure why it would fail on IE11, any ideas.

This is the complete error I get

I've seen the same behaviour when using browser.execute. In my case this happens when an argument to my function is an object containing keys with hyphens.

I solved this by JSON.stringify(arg) before calling browser.execute(function, arg).

So, my guess is that your consentRequestBody contains keys with hyphens.

I assume this behaviour is caused by org.openqa.selenium.ie.InternetExplorerDriver, but I'm not sure.
