    This is caused by something trying to render an asset tag to the page that doesn’t have a url or hash.

    If you read the stacktrace a bit more you should get an indication of where the issue is coming from.

    In our case we had the module Ebizmarts_Mailchimp installed.
    This was the exception:

    1 exception(s):
Exception #0 (InvalidArgumentException): Either remote URL or hashable content is required to whitelist

    Notice the vendor/mailchimp/mc-magento2/view/frontend/templates/mailchimpjs.phtml:8 at line #2

    The fix for us was to apply this patch

    If you’ve got cweagans/composer-patches installed you can just add this to your composer.json

    "extra": {
    "patches": {
        "mailchimp/mc-magento2":{
            "Either remote URL or hashable content is required to whitelist": "https://raw.githubusercontent.com/zero1limited/magento2-patches/eb137aaaf90ffa86add6566116d08723b1acfc26/patches/Ebizmarts_Mailchimp_mailchimpjs.patch"
        }
    }
}

    Then run composer install --no-dev and flush cache.

    keep it simple :

    override file mailchimpjs.phtml in path of ur theme : app/design/frontend/Luma/default/Ebizmarts_MailChimp/templates/mailchimpjs.phtml

    replace exist content by this :

    $url = $block->getJsUrl();
if($url){
    $render = $block->getRender();
    echo $render->renderTag('script',['type'=>'text/javascript','src'=>$url],'',false);
}
