How can I change Node version on a Flow?
The Node version configured on a Flow determines the minimum version required to run a Flow. It also controls which module versions that can be used. For example, if the Node version is set to 3.0 the Flow can not be used on a Node with version 2.5.6, but you can use modules that use features that are available in 3.0 Nodes. When adding modules to a Flow in the Flow Studio, only modules/versions supported by the selected Node version will be available. When connecting to a Node for a debug session in the Flow Studio, any Nodes not compatible with the current Flow will be grayed out.
You can change the Node version within the settings panel of the Flow Studio. After selecting a new Node version, use the "Update Module" option to update all modules to the latest version supported by the selected Node version.
