Hi, everyone
As you see in the message issues is not coming from asterisk configuration, and it’s related to wscat command, so the solution is to check version of your node and npm to detect that you have old versions by :
npm -v
node -v
then you have to upgrade node version to 14 by following this article Install the latest node version
good luck
