Keycloak: I can't add custom user attribute into the token? - keycloak

Question

My users has a birthDate attribute:
I created a mapper in client:
Yet it can't be seen in access token:
{
"exp": 1646589516,
"iat": 1646589216,
"jti": "7cee1468-8d80-4f14-a118-b07477c1e1e7",
"iss": "http://localhost:8080/realms/...",
"aud": "account",
"sub": "f:fd2a5a5a-c7a0-4e74-81a8-916a85885f98:...",
"typ": "Bearer",
"azp": "...",
"session_state": "efce7a63-2a8f-438d-b4a1-f5d979a00c81",
"acr": "1",
"realm_access": {
"roles": [
"offline_access",
"uma_authorization"
]
},
"resource_access": {
"account": {
"roles": [
"manage-account",
"manage-account-links",
"view-profile"
]
}
},
"scope": "openid profile email",
"sid": "efce7a63-2a8f-438d-b4a1-f5d979a00c81",
"email_verified": false,
"preferred_username": "..."
}
Can it happen that the keycloak caching somewhere? (I cleared the caches at Realm --> Caches)
I am desperate... Every tutorial does this and it is not working for me.
Update: I could test it on a server that is remote and it is working. Where the hell the keycloak is caching and screwing me?

Update2: deleted the keycloak & reinstalled so start from 0:
created realm: ep
created client: ep
Here we can see the user has an attribute birthDate with value my-custom-birth-date:
I go Clients --> ep client --> Mappers and create a mapper like this:
Clients --> ep --> Client Scopes --> Evaluate --> Evaluate button we can see that the birthDate can be found there (last row, also the default birthdate can be seen):
If I evaluate on the user P...o then you can see the access token does not contains the birthDate attribute:
If I use postman to request a token for this user, the access_token looks like this:
Still missing the attribute birthDate.
I repeated every action I did above and in the remote keycloak the attribute can be seen (the last one on the image):

So I found the problem:
Here is my keycloak folder and the path to it:
I copied the data folder to here thinking I won't need to recreate the realm/client/etc:
Whenever I reinstalled the keycloak, I deleted the keycloak-17.0.0 folder and reinstalled to the same place:
After I deleted both data and keycloak-17.0.0 and recreate the realm/client/mappers/etc, it is working perfectly...
No idea why did the keycloak checked for configurations/settings/caches a folder above in the tree...
