This code will be much easier without fancy functional programming:

for (var url of Object.keys(Runtime.cachedResources)) {
    if (url.indexOf("protocol.json") !== -1)
       
eval(WebInspector.InspectorBackendHostedMode.generateCommands(JSON.parse(Runtime.cachedResources[url])));
}

Done.

+    var protocols = protocolURLs.map(url => Runtime.cachedResources[url]);
+    for (var protocol of protocols) {
+        var code = WebInspector.InspectorBackendHostedMode.generateCommands(JSON.parse(protocol));
+        eval(code);
+    }
 }
