Error calling server API

obiwanjacobi commented 1 year ago

I have cloned the repo locally and followed the instructions. I get the client frontend at localhost:8080 but calling the server results in:

Http error (504) from server occured while making request to /api/IDojoApi/GetDistance

I also see periodically this error in the web (client) console (F12 in the browser): WebSocket connection to 'ws://localhost:8000/socketcluster/' failed:

There is nothing running on port 8000 so... what gives?

Please help ;-)

Hi @obiwanjacobi, thanks for reporting this issue. Unfortunately, I'm not able to reproduce it.

Triggering a call to the server via interacting with the application in the browser works fine for me when running from master:

And I don't see any of the socketcluster errors either

Are you able to give any more details, for example any error logs that you see in the terminal you launch the application from (using dotnet run)?

I can't reproduce this issue either. I've got no errors at all.

I'm sure I've had the WebSocket error at times when working on SAFE projects but it hasn't actually caused a problem.

mzvonar commented 1 year ago

I had the same problem on M1 Macbook with Node 18. For me the solution was:

either use Node 16 (according to this SO answer: https://stackoverflow.com/a/75057952/1409733)
or change http://localhost -> http://127.0.0.1 in the devServerProxy.target field in the webpack.config.js (according to this SO answer: https://stackoverflow.com/a/74464534/1409733)

obiwanjacobi commented 1 year ago

I'm on Node 18.15.0. I changed the localhost to IP address and that made it work. Thank you very much @mzvonar!
