Indeed redirect_uri wasn't consistent between conf, but after updating it 
nothing has changed. 

This is my service file now : 
{
  "@class": "org.apereo.cas.services.OidcRegisteredService",
  "serviceId": "http://localhost:3000";,
  "name": "OIDC",
  "id": 1,
  "clientId": "41ff9715-bd3e-473c-9888-e2d5a1364c2a",
  "clientSecret": "da31dc03-443c-4391-963b-86be2d9a4d45",
  "bypassApprovalPrompt": true,
  "generateRefreshToken": true,
  "evaluationOrder": 10000
}

And the URL called 
: 
https://{URL}/cas/oidc/authorize?client_id=41ff9715-bd3e-473c-9888-e2d5a1364c2a&scope=openid
 
profile email 
read:all&response_type=code&response_mode=query&state=T0xJV2hyOXFQdVY5anNsX1VsUURrMEVIRlREQ3JGRF9vYzFvZVBXRUpFNw==&nonce=eUFOTnU4NFVBQ0lDQjRteGcxV3E5V1I0N05OT0dzT29ubEwxQ3I4SE1uWg==&redirect_uri=http://localhost:3000&code_challenge=TxDYuTGk_M6AUKwC79VwUCZGE8WejkIwYAtcTkisvRk&code_challenge_method=S256&auth0Client=eyJuYW1lIjoiYXV0aDAtc3BhLWpzIiwidmVyc2lvbiI6IjEuMTkuNCJ9

I'm not seeing something that could cause the data causing the mismatch.

And the error doesn't give much detail on the specific issue (maybe my 
loggers aren't good ?)
