Error SMS

When I put a command to send and check the SMS option, this error appears, what do I do?

Cannot invoke "java.lang.CharSequence.toString()" because "replacement" is null - NullPointerException (... < HttpSmsClient:76 < *:94 < BaseProtocol:126 < CommandsManager:76 < ...)

Most likely you haven't configured the phone number for the device.

I'm testing the platform and this device from what I looked in the manual does not offer this option what to do?

I'm talking about the server side. To send an SMS to the device server obviously need to know what the phone number is. Where have you set it?

No, the sms would come from the traccar server.
Remembering that SMS already works in notifications, I wanted to test it now in the menu in commands

I understand that the SMS would come from the server. And that's why I'm asking where did you configure the phone number to send the SMS to?

I thought that with the traccar SMS app configured, I had to put the command and send it, since the notification is working.
Where do I put the number?

Sorry I already found the place.

Where did you put it?

I understand that you put it there now, but I meant where did you put the phone number previously?

I had not placed.

Thanks a lot for your help my friend.

Wait. So you never configured the phone number anywhere? How did you expect it to work in the first place?
