The definition itself seems to be fine: If I rename the

"UDA-Available", OpenSIPS starts. However, if I follow the examples
(e.g. module docs for aaa_diameter and here
https://www.opensips.org/Documentation/Tutorials-Diameter-Client-Server),
I fail to send the Diameter-Request:
11:10:14 ERROR ERROR: Invalid parameter '(((avp) && (((struct
msg_avp_chain *)(avp))->type == MSG_AVP) && (((struct avp
*)(avp))->avp_eyec == (0x11355467))) && pdata)', 22
Am I missing something? Can someone share some example code for
sending a SAR request? Is the documentation missing something?
Hello Carsten,
It is great to hear you are having fun with the module! With regards to
freeDiameter library errors (which are taken straight up from
/usr/include/asm-generic/errno-base.h, btw), I've typically seen two
codes being returned by the library:
#define EINVAL 22 /* Invalid argument */ -- most frequent
#define EEXIST 17 /* File exists */
Now, with *17* (already exists), this is returned if you are trying to
register a *duplicate* AVP as string name, but with different properties
(maybe diff type? diff code? etc.). As a general rule, the library
won't complain if we define a perfectly (?) identical AVP twice - it
will simply move on and return *0 *(success).
In your case, I suspect that the *22* (invalid arg) is still connected
to AVP duplication somehow, but the library returns *22* from some other
part of the error-handling code, as a small mistake. Especially since
you're saying /it works/ once you fix the name to something else.
To begin the troubleshooting, which dictionaries / fd extensions are you
loading right now? Because if you're loading the *dict_dcca_3gpp.fdx*
module, this one should already contain both of your AVPs (hence
explaining your errors!), check their definitions here on the
/libfreeDiameter/ GitHub:
Server-Assignment-Type
<https://github.com/freeDiameter/freeDiameter/blob/master/extensions/dict_dcca_3gpp/add_avps.c#L6999>
and User-Data-Already-Available
<https://github.com/freeDiameter/freeDiameter/blob/master/extensions/dict_dcca_3gpp/add_avps.c#L7138>
Best regards,
