TypeError: Argument 1 of mozRTCPeerConnection.getStats does not implement interface MediaStreamTrack.

[KaptenJansson]

Need to investigate why that happens on Firefox 40.0.3 (have not checked other versions).

[Sfinx]

FF42 - the same error

[KaptenJansson]

Still seeing the error in FF43

[KaptenJansson]

I believe we call on getStats in an incompatible way on Firefox (adapter.js shim does not shim this correctly).

[juberti]

OK, we should fix that shim then. I believe @alvestrand is working on fixing getStats, but it won't be until Q2.

[KaptenJansson]

I just tested this and I think this was fixed in adapter.js. I merged a new adapter version in #259.

[vshtokman]

I'm seeing this error in Firefox 45.0.1.

[silviapfeiffer]

Same here - happening again. :-(

+1

[KaptenJansson]

Sorry about this, will fix.

On a side note, appr.tc still works though, it's just that the info box is empty.

[silviapfeiffer]

It's more about test.webrtc.org which has stopped working completely on Firefox

[KaptenJansson]

Fix is in for review, just waiting for a reviewer to get it done.

adapter.js (the shim we use) has changed the way it handles getStats hence apps needs to be updated.

[KaptenJansson]

test.webrtc.org has now been updated and should work fine on Firefox now. Will take a look at apprtc now.

[giordanocardillo]

It's broken again on Firefox 57.

[usernolan]

I've been seeing this as well, FF57

[dnish]

Still an issue in FF58

[ShivaCherupally]

Can any one suggest me how resolve this issue..

This is happening when visiting microsoft teams, and cause video streams to not work.
