That's when running from inside the tester docker container.

But when running it all on the host machine, it works fine:

loopy:webid-provider-tests michiel$ NODE_TLS_REJECT_UNAUTHORIZED=0 SERVER_ROOT=https://localhost ./node_modules/.bin/jest test/surface/fetch-openid-config.test.ts 
(node:8545) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.

This issue must be caused by the docker.host.internal approach (which is necessary to harvest the cookie as described in https://github.com/pdsinterop/test-suites#running-with-manually-harvested-cookie), because if you just run the test normally, it does not get any 400 errors:
