[OpenSIPS-Users] Invalid parameter errors

[Ben Newlin]

Liviu,

Thank you for the quick response. I do see 2 such errors shortly after startup:

ERROR:core:pv_get_param: cannot get spec value
ERROR:core:pv_get_param: cannot get spec value

However, after that it just continues on with more of the same errors that keep scrolling. There is a variation of the scrolling errors that was I didn’t included before, in case it helps:

ERROR:core:comp_scriptvar: cannot get left var value
WARNING:core:do_action: error in expression at opensips.cfg:583
ERROR:json:expand_tag_list: Non string value in key
ERROR:json:pv_set_json: Cannot expand variables in path
ERROR:core:do_assign: setting PV failed
ERROR:core:do_assign: error at opensips.cfg:346
ALERT:core:pv_get_param: BUG: invalid parameter type 1836017711

There aren’t any other non-repeating errors. I have picked up your commit and will try to gather more information from it, but this issue is primarily happening in our production environment so it may take a bit.

Also, I haven’t completely verified this yet, but it seems that enabling TLS has made the errors stop somehow. Continuing to investigate that.

Hi, Ben!

The strange "...type 1836017711" errors seem to be caused by a poorly handed error condition (a secondary bug), which is now fixed [1]. If this theory holds, you must have a "cannot get spec value" error (or slew of errors) in the earlier section of your OpenSIPS log (possibly right after restart or shortly after starting to process traffic).

Could you please confirm/infirm the above?  If true, are there any other relevant errors thrown around that initial "cannot get spec value" error message?  Those error logs could be key to making progress in understanding the main bug.

Best regards,

Hi,

Since upgrading to 2.4.4 we are seeing the following logs scrolling nearly continuously on our servers:

It seems to be related to our use of the json module. We often pass json variable types as parameters to other routes and I believe the errors are caused by that. But it’s hard to say as there are a few different script lines referenced in the errors, but some of them point to return statements and other code sections that don’t really make sense. For example, line 583 referenced in the error above is:

  return(-1);

Any ideas?
