[BUG] Invalid HTTP response header sent with track event

[atkulp]

Description/Screenshot The App Insights track call sometimes returns an invalid HTTP response header that triggers a message in dev tools. I suspect this has nothing to do with this repo, but I'm not sure where to report it.

Invalid 'X-Frame-Options' header encountered when loading 'https://site.host.local/': 'allow' is not a recognized directive. The header will be ignored.

Steps to Reproduce Report an event which results in a call to the track endpoint (https://dc.services.visualstudio.com/v2/track)

• OS/Browser: Edge (Chromium)
• SDK Version [e.g. 22]:
• How you initialized the SDK:

Expected behavior All HTTP response headers should be valid across browsers

X-Frame-Options only allows DENY or SAMEORIGIN (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options)

Additional context Seen in Edge (Chromium) only so far. The header is completely missing in Chrome and Firefox (all current versions)

Firefox

Chrome

This is a backend issue and not an SDK one. Will raise an internal bug on the backend team to address this issue.

That's what I figured. Is there a place I should have been able to open this directly? Thanks for raising it internally for me!

I don't think they have a publicly accessible location, if they do I'll post here for future references

There is no publicly accessible location, the internal bug has been raised and for internal reference #12560602
