Symbol Server sourcemaps not showing due to CORS issue?

[burnnat]

Currently sourcemaps from Azure Artifacts symbol server are not loading for me, and looking in the "Source Maps Monitor" panel they all list the following error: "Unknown error requesting source map: Failed to fetch".

If I open the internal devtools console I see a lot of CORS errors that seem related:

I know this had been working for me previously but I haven't tried very recently so I'm not sure when that might have changed. If there are any other details I can provide, let me know!

Thanks so much for raising this. I'll make sure this is tracked by the team.

@captainbrosset Has anyone been able to look into this? I still see the same behavior despite following the setup article instructions exactly, and it doesn't seem to matter whether a PAT or Active Directory connection is used. If I launch the browser using .\msedge.exe --disable-web-security --user-data-dir="..." then the sourcemaps load great, but is there any possible solution that doesn't involve completely disabling the browser CORS policy?

@robpaveza for insights on the above.
