Yes it shows that my rest backend sends server error.
It's because freeradius also post an empty JSON body as shown in my first
post.

So why did rlm_rest send an empty JSON?

The case only happens  in dynamic-client.
While the user access authorization and accounting is working smoothly.

Sincerely

Please read the documentation:  http://wiki.freeradius.org/list-help
We don't need to see how your installed the server.  We don't need to
see the configuration files.  We don't need to see "radiusd -XXX".  This is
all clearly documented in many places.

The documentation says to post ALL OF the debug output.
What's happening here is not only that you're not reading the
documentation, you're not reading the debug output.  If you had read the
debug output, the issue would be clear.
The dynamic client code does not decode the packet.  So when it prints
out "Received Access-Request", there are no attributes listed after that.
And since no attributes have been decoded, there are no attributes to put
into JSON.  And therefore the REST call gets an empty json blob.
I really can't emphasis enough that it's necessary to read the
documentation, and the debug output.  I really don't know where else to say
that.  The issue is that mo matter where it's put in the documentation,
FAQ, mailing list, Wiki, etc., people just don't read it.
The only way to address these issues is to read the debug output.  When
you put enormous effort into doing everything *other* that following the
documentation and reading the debug output, you're just spending a lot of
time doing wasted work.
