Nodered ist failing every X Hours, can't find the Error

General
1

Hello,
my nodered Application is failing every X hours. After that I can start the application with a simple #dietpi-services start node-red

The Application runs on an RaspberryPi with "dietpi" as OS.

Is the Solax-cloud-api Module my Problem ?

Kind regards,
Steve

This ist the Log from #status node-red

That is a safe bet...

A node must handle its own errors to avoid crashing node-red.

Unfortunately, the source code doesnt appear to be on a public repository so there is no place to raise issues.

If you want a "workaround" then edit the file /mnt/dietpi_userdata/node-red/node_modules/@virtualbat/node-red-contrib-solax-cloud-api-client/solax-api-client.js - change the function setNodeStatus as follows...

        function setNodeStatus(res){
            if(res && res.status===200){
                if(res.data.success){
                    node.status({fill:"green",shape:"dot",text:"connected"});
                }else{
                    node.status({fill:"orange",shape:"dot",text:"Chech parameters: "+res.data.exception});
                }
            }else{
                node.status({fill:"red",shape:"dot",text:"Cannot connect: " + (res && res.status) || "unknown"});
            }
        }

Wow, that was fast :slight_smile: Thank you. I changed the code and will monitor it.
