jwt-authentication example

[johnrackles]

When I try to run the example locally, I get:

error - node_modules/jose/dist/browser/jws/flattened/sign.js (11:0) @ new FlattenedSign
TypeError: payload must be an instance of Uint8Array
null

Oddly enough, when I deploy it everything seems to work fine. Any Ideas how that happens? I checked, both vercel and my local machine are on node 14.18.1

This is due to the vm module isolation, the Indexed collections are not shared between where your code requires/imports libraries and the middleware execution context.

I've opened an issue about it vercel/next.js#30477

This is only the case when running outside of Vercel's own Edge Network.

For anyone stumbling upon this, it's fixed in v12.0.4-canary.4
