There is a lot of context missing from your question. You start by linking to
JSON attribute definitions documentation. Largely unrelated to the error you
quote.
1. Are you trying to return an attribute value, via groovy scripting, in a
service entry?
2. Or are you trying to rename an existing attribute to a new label via
attribute definitions?
If you are trying to return an attribute with a new label, via groovy
scripting, in a service entry (assumes original attribute named “giveName”):
…
attributeReleasePolicy:
{
@class: org.apereo.cas.services.ReturnMappedAttributeReleasePolicy
allowedAttributes:
{
@class: java.util.TreeMap
firstname:
[
java.util.ArrayList
[
‘’’
groovy{
return attributes[‘givenName’].get.(0)
}
‘’’
]
]
}
}
…
If you are trying to use attribute definitions to rename an attribute label:
Do you have
cas.authn.attribute-repository.attribute-definition-store.json.location defined
in your cas.properties?
Would expect:
cas.authn.attribute-repository.attribute-definition-store.json.location=file:/etc/cas/config/attributes.json
And then the following snippet in attributes.json
{
"@class" : "java.util.TreeMap",
…
"firstname" : {
"@class" :
"org.apereo.cas.authentication.attribute.DefaultAttributeDefinition",
"key" : "firstname",
"scoped" : false,
"attribute" : "givenName"
}
…
}

Subject: [EXTERNAL SENDER] [cas-user] Embedded Script Groovy in Attribute
definition
I am using this example for the JSON Attribute Definitions " Embedded Script"
https://apereo.github.io/cas/7.0.x/integration/Attribute-Definitions.html
It does not appear to be working, and throws an error:
2025-02-18 11:03:12,125 WARN

Any idea what could be wrong?
Thank you,
