max-connection-per-server not work

[billypon]

Version: 1.33.1
Client: aria2.js
Language: JavaScript

When I call addUri(['URL'], {'max-connection-per-server': 1}) via WebSocket, I can find the string max-connection-per-server=1 in the session file.
But when I call the same method via AJAX, will use the default config, and the string max-connection-per-server=1 is not found.

Why?

The value of 'max-connection-per-server' option must be string, not number!!!

Now it works: addUri(['URL'], {'max-connection-per-server': '1'})
