CORS error

[strukturart]

when trying to connect to the peerJS server I get the following error message:

ERROR PeerJS: Error retrieving ID (TypeError) 'referrerPolicy' member of RequestInit 'strict-origin-when-cross-origin' is not a valid value for enumeration ReferrerPolicy.

Hey @strukturart,
thanks for your report!

Could you tell us:

• which Browser are you using?
• do you host the server yourself?
• does the request fail or is it just a warning?

[strukturart]

which Browser are you using?
KaiOs 2.5.1
do you host the server yourself?
no
does the request fail or is it just a warning?
request fail

I’m sorry, but we probably won’t fix this if it’s not an issue with other - more common - browsers too.
With an estimated global usage of only 0.07%, KaiOS 2.5 is strictly out of scope for us. The browser engine was released almost 6 years ago!

If you need to support KaiOS 2.5, PeerJS v1.3 or below are still an option. They don’t use this policy.

Is the problem on the client side or on the server side? then I would adjust the version.

[franci2000]

Just the client.

Hey @strukturart,

We discussed this further internally. KaiOS 2 is still not a target for us, but there might be value for everyone in customizing the referrer policy. I pushed a patch to the rc branch.

You can get it from npm i --save peerjs@rc, or eventually in the next release. Then just set your desired policy:

new Peer({
	referrerPolicy: 'origin-when-cross-origin',
})

Thank you!
