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
