We have several subflows in our Nodered flows, and they were working fine previously.

However, they were not working until a month ago. the subflows are not receiving any data from other flows.

And I noticed that there is an error in node-red-node-email in the installed palette list.  
Error message: Error : Requires nodejs version \>= 8.  
The version of this palette is 1.6.2

May I ask how to resolve this issue please?  
Do we need to upgrade the nodejs version in the node-red services on cloud ? and how?

Thanks a lot.

Yes you do need to upgrade your version of node.

What cloud are you running on? How did you install Node-RED?

Hi Knolleary,

I am using the Node-Red services on IBM public cloud.  
The services was installed automatically .

And how should I upgrade my node version ?

Thanks a lot.

1. log in to the IBM Cloud dashboard and go to the dashboard page for your application
2. in the bottom right corner is a box where you can enable the 'continuous delivery' feature. Once enabled, this will create a git repository where you can edit your application code and a deployment toolchain that will deploy changes.
3. Edit your `package.json` file and change the `engines` entry to say `10.x`. Then push the changes back and your application will be restaged.

Hi Knolleary,

When I changed the engines entry to 10.x , it failed during the compile.  
(Failed to compile droplet: Failed to compile droplet: exit status 1)

But it works when I changed the engines entry to 8.x.

And the problem solved .

Thanks a lot.
