If you're using git, you may need to pull with --recurse-submodules to pull the third-party sources (if you're using the releases, use the .7z not sources which will also correctly contain submodules sources). Otherwise the marketplace 4.24 version is currently submitted pending approval.

I'm using release archive which unpak to the ue-source\Engine\Plugins\Marketplace\SocketIOClient folder. As I can see archive contain all submodules.

I tried sources and pak with binaries (*.7z) and the result is the same.

I've run into the same issue when trying to cook / package the client as a standalone. The problem is the use of DeveloperTool in the .uplugin definition. Can't find any documentation on why / how this has changed but the correct value should be Editor. Switching to Editor works. Had the same issue with our own plugins.

This is the offending line: https:/getnamo/socketio-client-ue4/blob/f682bcc51a16343f7200bad541353f1878c076eb/SocketIOClient.uplugin#L77

[getnamo]

That makes sense. With 4.24 the developer category was removed and I thought developer tool was the correct context for that one, but it seems editor is the correct upgrade path. Thanks @marwanhilmi for spotting the fix!

Fix added: 089e8d9, repull master or get the latest release: https:/getnamo/socketio-client-ue4/releases/tag/1.3.2

@marwanhilmi Thanks a lot. @getnamo The latest release is built without errors.
