I'm trying to update entity attributes via the workspaces/{namespace}/{workspace}/entities/batchUpdate URI but I keep getting "Lock wait timeout exceeded" errors. The first time I tried, the response was:
<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>502 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered a temporary error and could not complete your request.<p>Please try again in 30 seconds.</h2>
<h2></h2>
</body></html>
but since then, the API keeps responding with a json rawls stack trace:

This is not the first time I've encountered this issue
