https://deno.land/x/djwt@v1.3 is returning a 404 at the moment

https://deno.land/x/djwt@v1.2 is the last one available.

deno.land/x downloads and stores your repository contents every time you create a git tag. We only do this once for every tag. This ensures that the contents we serve for a specific version can never change. Our service needs to get informed whenever a new tag is created. For this purpose we use GitHub webhooks.

Maybe there is an issue with the webhook configuration ? Or is it something on their side ?

My bad, did not intend to add this file.

I just upgraded to Deno 1.4.0, which I run with the --unstable flag, and got this errors in my project. They are making the typescript check stricter by default: https://deno.land/manual/getting_started/typescript

Fixes errors in Deno 1.4.0 with --unstable stricter typescript

Fixes errors with deno 1.40 and --unstable flag

With the release of Deno 1.4.0, there have changes to typescript flags that breaks library that are not explicit when importing / exporting types

This fixes TS1371 that raises in deno 1.4.0 with the --unstable flag

Addresses #243

Running Deno 1.4.0 with the --unstable flag raises a lot of errors:

Chrome refuses websocket connection if the header Sec-WebSocket-Protocol is set, because it's not returned by Deno.

Error during WebSocket handshake: Sent non-empty 'Sec-WebSocket-Protocol' header but no response was received

MDN documentations specify that the server should return a header with the selected protocol in that case: https://developer.mozilla.org/en-US/docs/Web/HTTP/Protocol_upgrade_mechanism#:~:text=The%20Sec-WebSocket-Protocol%20header,header%20included%20in%20the%20response.

As far as I can see, there are no way to specify custom headers in acceptWebSocket

https://github.com/denoland/deno/issues/3539#issuecomment-643461959 reports the same issue
