Can not add "dev=true" to the url

Hi @Roy ,

“your_first_app” template is working fine. HAR format is a JSON-formatted archive file that records all network interaction between a web browser and site.

Please follow the steps over here to generate one - How to generate HAR file to export and analyse network request logs?

Not sure which app location you’re trying & manifest contents - that’s the reason I’ve asked the app zip. I’m also attaching the zip that’s scaffolded the same way & working fine for me below just to cross verify with yours (if any).

service-test.zip (4.4 KB)

Thanks
