static-web-apps-cli: swa 1.0.3 with Node18 - Can't reach api endpoint

Describe the bug The last version of the swa cli (1.0.3) doesn’t seem to work with NodeJS LTS 18.12.1 on a Blazor WASM with dotnet functions. The swa cli can’t connect to the api endpoint, but it works outside the swa cli either by running it via swa start or func host start:

[swa] ✖ Could not connect to “http://localhost:7071/”. Is the server up and running?

To Reproduce

> swa start http://localhost:5000 --run "dotnet watch run --project src/Client/Client.csproj" --api-location src/Api -V silly

Hey @arobthearab , @jouz3 we’re able to reproduce the same issue locally. Seems like something is breaking with azure function core tools v4 with Node18 installed. We’re investigating this issue and will get back to you soon. Meanwhile please try to downgrade the version of Node 16. Please feel free to contribute if anyone has any discoveries. Thanks.

Hi all, The team is currently investigating this issue and will keep you posted on our findings. Node 18 is still in public preview, so kindly bear with us while we investigate and figure out the compatibility. We are expecting to get the fix within a month. Meanwhile, please resort to Node 16. Apologies for the inconvenience!

Just wanted to follow-up and mention that you should also make sure you’re not being dumb like I was and make sure you cd into the actual project directory first before running the tool. 🤦‍♂️

Though it would be nice if the CLI could mention that no SWA config was found or something to give the developer a hint.

Something I found odd is this issue with node 18 is happening in Windows 11 (in my case), but is working fine in Linux (Ubuntu) I am using the latest swa (1.0.6) btw

I have also the “Could not connect to “http://localhost:7071”. Is the server up and running” issue when node 18 and swa 1.0.4 With node 16 and swa 1.0.4 everthing works as expected
