@sushilca98 you don't need to change anything in the server.py file. All you need to do is run it alongside the client app.

Note, running the server is via the command python datafeed/server.py. Do this in a separate command line and make sure you're running the command within the repository (i.e. your command line's present working directory is the repository). On a different command line, run the client via npm start. (this is assuming you're command line is also in the repository and you've done npm install already)

Hello Sir,
I tried the way you explained but when I run the command
C:\Users\sushi\JPMC-tech-task-2>python datafeed/server.py

Then it gives a response as
Traceback (most recent call last):
File "datafeed/server.py", line 26, in
import dateutil.parser
ImportError: No module named dateutil.parser

I also ran the separate command as
C:\WINDOWS\system32>cd\Users\sushi\JPMC-tech-task-2

C:\Users\sushi\JPMC-tech-task-2>npm start

Then I was able to go to Bank and Merge Co Task 2 but when I try to start streaming data it gives me same result as

NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://localhost:8080/query?id=1'

Please check the screenshot and help me to get the result.

Glad you were able to fix the issue @sushilca98 . The issue you encountered regarding running the server script is also discussed in the slides in the trouble shooting section for the OS you're using. This has something to do with installing the missing python package i.e. python date-util via pip

I am facing the exact same error right now....
I also have the dateuntil error when the server starts
I do not know how to solve it.

Can anyone help me at the earliest...?
