Tests fail to pass even though it works as expected about phase-1-sending-data-with-fetch

[sheenasany]

Still having this error with students who are trying to pass the first test, even though the post request is working on the DOM.

Uncaught TypeError [ERR_INVALID_ARG_TYPE]: The "stream" argument must be an instance of Stream. Received an instance of Socket

A suggestion that could fix this issue would be to downgrade your node version. Like so:
nvm install 16.14.2
nvm alias default 16.14.2

Or! If you're still working on this lab, just want to downgrade your current version just for this lab, try this:
nvm install 16.14.2
nvm use 16.14.2

You could also delete the node modules and the package-lock file and reinstall dependencies.

That should fix the issue and get the tests to pass or just make the tests easier to read.

Just wanted to echo this error. I am experiencing it as well: Uncaught TypeError [ERR_INVALID_ARG_TYPE]: The "stream" argument must be an instance of Stream. Received an instance of Socket.
I don't know much about Stream instances. Reading this resource and feeling confused as to why we are getting a websocket instead of a Stream instance?

Had the same issue.

I had the same problem!

Issue still persists.

Downgrading node to 16.14.2 as referenced above did the trick. Thanks for the advice!
You can check your version of node by running this command in your terminal:

node -v

and then you can downgrade with these commands:

nvm install 16.14.2
nvm use 16.14.2

then after you complete the lab you can change back to your current version:

nvm use [version number listed when you ran first command]

Hey all! Thanks for all the help with this issue. It should now be fixed and should work with either Node 16 or Node 18 🙏
