Hi everyone! I've started seeing this deprecation being reported via Reporting API (through a ReportingObserver and Reporting API pings) on a few sites that are being measured for RUM.
The actual deprecation report was very hard to decode, as all that was included was the ID (4201) and a confusing message (which looks like an internal error message). e.g.: { "body": { "anticipatedRemoval": null, "columnNumber": 12345, "id": "4201", "lineNumber": 1, "message": "Deprecation messages are stored in the devtools-frontend repo at front_end/models/issues_manager/DeprecationIssue.ts", "sourceFile": null }, "type": "deprecation", "url": "https://example.com" } It took some help from Yoav to understand 4201 is this specific issue (I think). With the details here, I can begin to understand (as a developer) how to address the reports. I filed a Chromium bug to ask for more details in the deprecation report: https://bugs.chromium.org/p/chromium/issues/detail?id=1368607 On Monday, September 12, 2022 at 8:26:29 PM UTC-4 andr...@google.com wrote: > CC @Cheney Tsai, @Una Kravets, @Kadir Topal > > From a DevRel perspective, the three questions in my mind are: > > - Are affected developers aware of the change? > - I understand they were notified via a console warning / > deprecation warning.
