Why is YouTube making requests to ourdomain-example.com/error_204

We have a WordPress blog running under via a reverse Proxy under ourdomain-example.com/blog which embedds YouTube videos.

Now we are seeing requests in the chrome network tab to

 POST https://ourdomain-example.com/error_204?a=logerror&t=jserror&type=SyntaxError&msg=Failed%20to%20execute%20%27postMessage%27%20on%20%27Window%27%3A%20Invalid%20target%20origin%20%27data%3A%27%20in%20a%20call%20to%20%27postMessage%27.&line=Not%20available&level=WARNING&client.name=1

This requests lead to problems in our main software (Magento, under '/', showing CSRF problems)

We could just block those requests in the server but we want to understand why they are made.

Did anybody see those requests before?
