Keycloak 19.0.1: multi value user attributes

Hi,

I am running latest version (19.0.1) and I cannot (or I don’t know how to) configure multi value attributes for an user.

In the previous versions I used to use the “##” trick but it seems this is not available now, or…? The usual config (“multi-value” flag, mappers, etc) are configured as before, when it used to work.

I am using standard theme, no customization, same problem exists for me in dev or production mode.

Are there any changes in this area? no info in upgrading guide

Thanks,

LE: what it happens is that in the user profile returned, when configuring a multivalue mapper for an attribute with value “val1##val2” I get [“val1##val2”] instead of expected result [“val1”, “val2”]

It seems Keycloak 19 has some issues with multi user attributes:
