Found just now the requirements for the latest package! image Seems like this is probably what's causing the issue.

Hello @Venomz101 , as the comment above suggests, try updating your Node-RED and Node.js versions.

This node was designed for Node-RED version 1.1.3 and Node.js version 14.

We will be closing this issue, if there is a need to revisit the subject, please open a new one. Thank you very much.
