For this kind of question about why it is able to work, I think you should delve into the code to analyze the problem.

You required to read POST argument in balancer_by_lua*.

As per documentation, ngx.req.read_body() is not available in the balancer_by_lua*

In order to access body value in the balancer_by_lua, it is suggested to read required value in the rewrite_by_lua* or access_by_lua* phase and store value in the ngx.ctx i.e request context.

you can access ngx.ctx in the balancer_by_lua* and take required operation
