The args are right, the hltm content dont have any unclosed tags, but simply get this error...

The funniest thing consists in the fix for this problem. Just rerun and rerun the request without any changes. And at 5th or 6th try (ususally) the problem is fixed...

When i dont get error, i obviously get response.status 200 and json object as response. But sometimes i get 500 status with that NOT JSON body, that raise the exeption:

<html>
<head><title>500 Internal Server Error</title></head>
<body>
<center><h1>500 Internal Server Error</h1></center>
<hr><center>nginx/1.20.1</center>
</body>
</html>
