Posted almost 2 years ago

€18-36 EUR / hour

I have a node js grpc server and client. The code was written with callback but due to racing conditions it is rewritten in Async await on the server side. But now on the server side it looks ok. But on the client side the function call is done, the server gets the data but when it returns the client does not receive it. I need someone with experience in Node JS, async await troubleshooting and also GRPC experience. If you are the person to help me i will submit some sample code off the client and server to reproduce and hopefully resolve the issue.
