SMS - app.lua:48 attempt to call a nil value

[nickbh]

I am trying to send an outbound sms message and I get the above error.

I followed the below link and fixed the chatplan that was default.xml by copying the one mentioned in that below thread.

SMS

Is the SMS app (https://github.com/fusionpbx/fusionpbx-apps/tree/master/sms) still the proper way to enable SMS inside of FusionPBX? I have looked at all of the threads (some quite dated) and want to make sure I am moving in the right direction. I see Messaging under applications, but not sure...

1. Looking in the freeswitch.log

stack traceback:
/usr/share/freeswitch/scripts/app.lua:48: in main chunk

2. Browsing the app.lua, at line 48 -
--route the request to the application
--freeswitch.consoleLog("notice", "["..app_name.."]".. scripts_dir .. "/app/" .. app_name .. "/index.lua\n");
loadfile(scripts_dir .. "/app/" .. app_name .. "/index.lua")(argv);

3. based on error, i am trying to execute app.lua without proper parameters (argv), but the call from chatplan/default.xml provides :

<action application="set" data="final_delivery=true"/>
<action application="lua" data="app.lua sms outbound"/>
4. within the scripts_dir, there exists app/sms/index.lua
/usr/share/freeswitch/scripts/app/sms/index.lua


5. just a note, since bandwidth is using apiv2, had to add application id in a curl call.

I would appreciate any help.

Thanks.

This is fixed. It was my fault - after writing what I had done, it seems that the addition of applicationID was breaking the index.lua in the sms. Leasson learned and thank you.

Here is the line that needs to be added for someone else using Bandwidth sms apiv2.

Original:
-- cmd="curl -v -X POST " .. api_url .." -u " .. access_key .. ":" .. secret_key .. " -H \"Content-type: application/json\" -d '{\"from\": \"+" .. outbound_caller_id_number .. "\", \"to\": \"+" .. to .."\", \"text\": \"" .. body .."\"}'"

Updateded.
cmd="curl -v -X POST " .. api_url .." -u " .. access_key .. ":" .. secret_key .. " -H \"Content-type: application/json\" -d '{\"from\": \"+" .. outbound_caller_id_number .. "\", \"to\": \"+" .. to .."\", \"text\": \"" .. body .."\", \"applicationId\": \"" .. application_id .. "\"}'"

Added to above file:
if (settings['sms'][carrier..'_application_id'] ~= nil) then
if (settings['sms'][carrier..'_application_id']['text'] ~= nil) then
application_id = settings['sms'][carrier..'_application_id']['text']
end
end

Hi i have the same problem , i didn't understand where to change the original with the Updateded

 

[nickbh]

changes I made were in the /usr/share/freeswitch/scripts/app.lua

I suspect you mean in /usr/share/freeswitch/scripts/app/sms/index.lua.

And thanks for the info on v2 compatibility. I originally wrote the Telnyx add-on under v1, and never bothered to go back and update to v2.

FYI, on the inbound side, I believe someone mentioned that there may also be breaking changes related to MMS attachments under v2, so you may want to verify that.

Thank you, I will look into this
