Hello
in /authorize my response_type is set to id_token, but in the response i receive there is the # that don’t allow me to get access to the id_token.
the authorize request:
https://YOUR_DOMAIN/authorize?response_type=id_token&code_challenge=CODE_CHALLENGE&code_challenge_method=plain&client_id=CLIENT_ID&redirect_uri=https://MY_DOMAIN/callback&scope=profile&audience=AUDIENCE

response:
http://MY_DOMAIN/callback?#id_token=eyJhbGciOiJSUzIsknvsfklvnmsdölvmsdlöbvfmslbödfmlöbdfmblömfblöm blxöfbmlföbm lögm ndfmfngm fglnögwLmN

i looked around but so far nothing seems to fix my problem, even changing the

response_mode
