I am trying to verify on my backend side (node.js) user's token. Based on the official documentation docs I should download first all JWT from
https://cognito-idp.${region}.amazonaws.com/${UserPoolId}/.well-known/jwks.json
But for some reason this address doesn't exists (of course with valid region and UserPoolId). Everything should be configured well because signup, it's confirmation and login works perfectly, users are added to the pool, I've got token. Any idea what can be wrong ?
For me the following works to access the JWK Set (basically replaced the region and user pool id in the url above).
https://cognito-idp.us-east-1.amazonaws.com/us-east-1_O2vEE1sUF/.well-known/jwks.json
https://cognito-idp.us-east-1.amazonaws.com/us-east-1_O2vEE1sUF/ should be coming from your iss field.
