On clicking Start Streaming Data on Browser, I am getting following error: - NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://localhost:8080/query?id=1'. ss1 ss2 ss3

I am using python 3.7.2 and windows 10.

same error encountered any solution?

harmankaur23 commented 4 years ago

I don't know if it would work for you, but I went to JPMC task1 folder and ran server3.py there instead, and npm start from the task 2 folder. Weird but worked:)

Same error... I tried changing the ports from 8080 to 8085 in the server3.py and datastreamer.ts codes.

Python version 3.8.1, and OS windows Any suggestions would be great.

I got a solution to this problem. I ran python datafeed/server3.py in one cmd(run it as administrator) and in another I ram npm start, so thus, I didn't get this error again.

Yes, I've been doing that too... Is the server cmd (The one in the admin mode) supposed to show any output though? Because it shows me an error to the command : "python datafeed/server3.py" error msg: {Traceback (most recent call last): File "datafeed/server3.py", line 26, in import dateutil.parser ImportError: No module named dateutil.parser}

But when I run the command : "python3 datafeed/server3.py" it doesn't show anything.

see you need to now install dateutil via pip install python-dateutil. This can be only done if you have pip. If pip is not installed then install pip first then go for dateutil.

@Kam149, Thankks for replying!!! Actually I've installed those too... Then I even tried to manually copy and paste the dateutil folers inside datafeed. Still didn't work. If I execute : python3 datafeed/server3 - it gives no error in the terminal ( however the "Network error failed to execute send" shows on the browser) but with : python datafeed/server3 - it gives this error now: {Traceback (most recent call last): File "datafeed/server3.py", line 26, in import dateutil.parser File "C:\Users\menon\JPMC-tech-task-2-PY3\datafeed\dateutil\parser__init__.py", line 2, in from ._parser import parse, parser, parserinfo, ParserError File "C:\Users\menon\JPMC-tech-task-2-PY3\datafeed\dateutil\parser_parser.py", line 42, in import six ImportError: No module named six}

Python3 is not going to work because this command does not work on Windows. You have to try with python command only. Now the error is in this file of date util which you copied in datafeed. So I think you should delete this file and then again try: - pip3 install python-dateutil. (If earlier you didn't try installing with pip3). Else you can delete whole of the folder and repeat those steps. Because I think that some of your file corrupted.

Oh Okay... I'll try that. Thanks a lot @Kam149

I forgot to start the server3.py file in another error mess and run npm start. I'm just saying don't forget to run server.py in parallel before you execute npm start or it won't work
