500 error while syncing project

Hi Guys,
Getting 500 while syncing project. Anyone else facing the same issue?

Plasmic error: Error: request failed with status code 500. The response is
  <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Internal Server Error</pre>
</body>
</html>

It was caused by a combinational variant. It’s resolved after reverting the changes. However, it would be great to have informative error message.
