ReportingObserver API is not working. nothing happened in sample site

I am writing to you today regarding my recent attempts to use the ReportingObserver API on a sample site provided by MDN, as well as in my own code, and experiencing some difficulties with it.

In the sample site (deprecation_report.html), when I clicked the button, nothing happened.

Additionally, I attempted to use the API in my own code, following the example provided on the MDN site, but encountered similar issues where nothing seemed to happen.

I have included additional information below for your reference:

  • Browser used: Google Chrome version 111.0.5563.64 (Official Build) (arm64)
  • Operating System: MacOs Ventura 13.2.1

Thank you for your time and assistance in advance.

Hi @yjyoo and welcome to the community :wave:

I can confirm your observation for Chrome 111 and Chrome Canary 114 on Windows 11.
Can you please open an issue on the MDN GitHub for the Reporting API page?<!--+Do+not+make+changes+below+this+line+--> <details> <summary>Page+report+details<%2Fsummary> *+Folder%3A+`en-us%2Fweb%2Fapi%2Freporting_api` * * * *+Document+last+modified%3A+2023-02-19T10%3A03%3A58.000Z <%2Fdetails>

Thank you very much and have a nice weekend.
