Just tried, issue remains. The error is saying that you cannot convert a function to JSON.

The stack trace shows that the tree object contains a function when it’s passed to the encodeMenuAsJSON function, so the $.toJSON(tree); statement throws an error.

If you do a console.log(tree); inside the encodeMenuAsJSON, you’ll see that the tree object has a color_presets object containing a function called remove.

In the readMenuTreeState function definition, line 1692, if you comment out the color presets attribute, the save button works fine.

return {
tree: tree,
//color_presets: $.extend(true, {}, colorPresets),
granted_capabilities: AmeCapabilityManager.getGrantedCapabilities()
};

This should give a hint on how to solve the issue.
