Additional Information

Hi @shefalijoshi, I have found only one place of the Object.hasOwn() method usage - Telemetry API.js. I assume that the issue refers to the Safari browser that the method is in development and should be supported in a pre-release version.

We can solve it by reimplementing

Object.hasOwn(requestProvider, 'request')

to

Object.prototype.hasOwnProperty.call(requestProvider, 'request')

In this case, I would also recommend adding the following piece of code

typeof requestProvider.request === 'function'

as a && condition to be sure that the request property is also the function - see Telemetry Providers.

Testing

• confirm you can use the historical request functionality of telemetry api. So just view historical telemetry and confirm no errors in console
• try multiple browser types
