Answer 1

i hope this solution solve your problem and save many hours for anyone that have this problem

you can just use bindEmitter to solve the problem

app.use((req, res, next) => {
    httpContext.ns.bindEmitter(req);
    httpContext.ns.bindEmitter(res);
    var requestId = req.headers["x-request-id"] || uuidv4();
    httpContext.set("requestId", requestId);
    console.log('request Id set is: ', httpContext.get('requestId'));
    next();
});

I am having the same issue. Attempted the bindEmitter solution above and that did not work.

After a few trail and errors REF#1 removing the 'Content-Type': 'application/json' header from my clients POST invocation allowed values in the context to be set/retained.

This led me to suspect there was an issue with how the body-parser(v1.19.0) middleware and express-http-context(v1.2.3) interacts.

When I reversed the order of the middleware such that body-parser comes before express-http-context httpContext was working as expected (without having to do REF#1 ) E.g:

app.use(bodyParser.json()); //must come before
app.use(httpContext.middleware);
