Objet : Re: [SR-Users] Script @Startup
Can you get from gdb the output from the next command:
frame 11
info locals
list
frame 1
info locals
list
p *res
p* s
Then, the issue is accessing select variables from config parameters, like $sel(...). Apparently they are not initialized completely at that time. I tried a quick fix with the previous patch. Can you do the event route without using $sel(...)? What is exactly the avp db query you have in the event route?
Cheers,
Daniel

Hi, maybe event route core:worker-one-init is helpful to you.
