Invalid module - code ERR_INVALID_MODULE_SPECIFIER

[frandiox]

This error is thrown when using Node >= 16.2 due to this breaking change: nodejs/node#37468

Downgrade to 16.11 or 14 for now. This breaking change might be backported to 14 as well.

Thanks for notifying here! I was on a quest to figure this out when it occurred to me to come see here. Unfortunately, I seem to be getting the same problem on Node v14.18.2... I had just upgraded to 16 to see if it would fix it.

And this is the day I pick to integrate Vitedge to my project 😅

Same error on v14.17.6, a different one for v14.16.1 and v.15.15.5.

TypeError [ERR_INVALID_RETURN_PROPERTY_VALUE]: Expected string to be returned for the "format" from the "loader getFormat" function but got type object.

@alexturpin I'm not seeing the issue with latest 14 🤔
Is your project using TS or JS?

[alexturpin]

@frandiox TypeScript. I also tried ts-node 10, 9 and 8 to no avail.

[frandiox]

@alexturpin 0.17.4 should have these issues fixed. Can you please give it a try?

[alexturpin]

@frandiox yes, thank you very much for the quick fix!

I'm getting this error with reactesse-edge-template, regardless of node version. npm / yarn also makes no difference. Manual steps from the getting started page results in same. Running on windows.
